Caig DeOxit is mentioned in a number of FORD and HONDA service bulletins! So whether you're fixing a Tesla Coil (great for RF ground bolt connections) or a Tesla Electric Vehicle (EV)... try DeOxit. It has also been featured in various Automotive, Boating and Motorhome magazines! This FDA bulletin also mentions DeOxit - because it helps prevent "fretting corrosion" (contact failure) in critical health-care, hospital or medical equipment!

You cannot possibly believe how good DeOxit and DeOxit Gold (formerly Pro-Gold) are at solving those intermittent contact problems that seem to plague almost all electrical products at some time - until you try it! Personally, I (Peter King) recommend these products myself because I know they work! I have fixed a mobile phone, a cordless phone, an electrical powerboard and an expensive Kenwood HiFi using the DeoxIT product (all within one week of first receiving the product). Problems which had plagued these products in my home and my office for years! My old contact cleaner just could not do what DeoxIT can. Please read my testimonial and many others below. You will find uses for DeoxIT in the home, in the office, in the factory, on motorbikes, cars and trucks, in boats and aircraft. In industries such as television and radio, telecommunications, security, medical and computer equipment, avionics, photography, audio and video. In fact, anywhere there is electrical or electronic products and possibly more (e.g. some people swear that it can be used on guitar strings). DeOxit is particularly good for battery contacts in digital cameras (Click here), mobile phones and any device used in outdoor or harsh "damp" or "humid" environments. Also helps prevent corrosion should batteries leak (e.g. alkaline batteries) and on car or truck battery terminals to prevent the formation of the white powder or ashy deposit. Also, we've discovered recently, DeOxit can be used on the metal surrounds to prevent further corrosion on connectors (such as D25) after being exposed to rat's urine... or other corrosive conditions! DeOxit can also be used for cleaning potentiometers and slide pots but is not recommended for cleaning keypads which use carbon based contacts... use DeOxit on the metal contacts only and then flush any residue with CT-CC350.

Ideal for use on ALL electrical contacts including; battery contacts, mobile phone SIM cards, smart card contacts, computer connections (USB and other ports and inside on power terminals and PCB edge-connectors), memory cards and sticks (e.g. SD, SDHC, MicroSD, MiniSD, MMC, SmartMedia, xD, CF-I cards) and many, many other applications! Also great for use on vintage and antique radio devices and other equipment (computer, electrical and electronic) especially those using plug-in valves! Fantasic for removing oxide from Printed Circuit Boards (PCBs) and stopping oxidization of the copper! If you're having trouble soldering components on a PCB... try using Deoxit first!

Personally, DeOxit is the product I reach for automatically when I suspect a contact problem or when I know a product is to be used in a 'harsh' environment! Outdoors, high humidity or industrial environments DeOxit is the answer! Use it BEFORE the problems start! Having noticed that the head of screws on desktop power supplies (when used in harsh or humid environments) seem to be the first to rust, I now use a small dab of DeOxit on the head of screws as a preventative measure (as a rust inhibitor).

For general cleaning I use a large spray can of CONTACT CLEANER (CT-CC350). This is a precision electronic product cleaner that evaporates and leaves no residue. Great for flushing away dust and dirt from all sorts of things and is safe on most plastics! We recommend that DeOxit spray be used on hard-to-get-to components such as pots and switches and then flush any residue away with Contact Cleaner! Note, it's important to flush away excess DeOxit on any sensitive areas such as in audio circuits. Our recommendation is not to bother purchasing FaderLube but rather use DeOxit and flush with CT-CC350 or CRC-2016. DON'T PAY "$27.50" FOR "CO CONTACT CLEANER" BUY "CT-CC350" CONTACT CLEANER INSTEAD!

KDG100L-2DB (shown above centre)
Dual pack with one 7.4ml bottle (50mm high) of DeoxIT D100L-2DB and one 7.4ml bottle of DeoxIT Gold G100L-2DB. This kit is best for delicate equipment where the application must be applied precisely. Remember that all excess must be cleaned off delicate equipment! This is the best pack as it is less wasteful than the sprays and allows you to apply the DeOxit precisely. The bottles come with small brushes in the cap that allow you to apply DeOxit immediately or you can use the cotton buds or wipes supplied in this pack. To apply DeoxIT to sockets, apply it to the exposed pins of the plug first and then insert the plug into the socket!

The DeOxit bottles look tiny (they easily fit into any toolbox or glovebox), but you only need to use a very small amount on the metal contacts only - unlike other contact cleaners that evaporate and can be used for general cleaning! The small DeOxit bottles will last a long time even when you use it continually on all devices as a preventive measure!

JustAnotherEngineer - I'm an electrical engineer and for over 30 years I have relied on Deoxit for cleaning, rejuvenating, lubricating and protecting electrical connections. It is very close to being magical - cleaning noisy switches, intermittent relays, and potentiometers (volume controls). Once applied, you will get many more years of additional service.
Boeing Company - We have been using DeOxit products on switches, contacts and edge connectors and they are considered "Preferred Products" at Boeing.
Bose Corporation - DeOxit is an excellent product for removing oxidation and contamination from dirty switches & controls and reducing intermittent contact problems. We have been using DeOxit products with great success for over 35 years.
Hewlett Packard - Consistent intermittent connection failures on PC board edge connectors for our micro automation equipment have been eliminated by using DeoxIT®. It has been indispensable in reducing down-time on our equipment.
Honeywell Inc. - DeOxit is great stuff. We use it on feedback slide-wires, edge connectors, & relay contacts in industrial process controls.
News & Sound Studio Editors (Radio World) - The DeoxIT® Gold works great. I used it on some old tube equipment and it eliminated a loud hum that I thought was something more serious. DeoxIT® D-Series also got rid of the recurring contact noise in a rotary control that usually returned after using other sprays. Even works on keeping oxidation from metal panels and knobs.
Rane Corporation - People call me daily asking for recommendations for cleaners and lubricants. Most everyone has tried something less than DeoxIT®, and after using what we authorize, the results are always positive, sometimes bordering on miraculous. Rane includes instructions for using DeOxit for maintenance in it's operator and instruction manuals for mixers, crossfaders etc.
Tektronix - We use DeoxIT® Gold to protect virgin edge connectors, DeoxIT® D-Series contact cleaner to eliminate intermittent problems on primitive tin-to-tin connectors (which tend to vibrate) and will be using DeoxIT® Gold in the field for gold connectors . . . . . excellent product.
Xerox - Corrosion problems on very sensitive connectors have been an annoying problem for us. We have tried many products without success until we tried DeoxIT® D-Series and DeoxIT® Gold. They are the only products that have worked perfectly. We highly recommend them.
Other companies using* DeOxit... ABB, Agilent, Daktronics, Dolby Labs., Dover Elevator, Eastman Kodak, Federal Express, General Electric, Harman (Crown Audio equipment), Hollis (diving gear), Intel, Intermec, John Deere, Juergensen Marine (diving gear), Komatsu (trailer maintenance kits), Krohn-Hite, Logitech, McIntosh Labs, Motorola (pagers & battery maintenance), Nokia, Philips Healthcare, Roland, Switchcraft, Teledyn-CDL (subsea and diving equipment), Union Pacific, Wayne-Dresser and more! *or suggest using DeOxit in their manuals.

OTHER USES: 1. Cleaning model train tracks and all connections with motorized models such as model racing cars, model aeroplanes, boats etc. 2. All electrical contacts/connections in construction sets such as lego, fischertechnik, mechano etc. Can also be used to preserve any metal parts from oxidation and stop those squeaky bearings on electric motors! 3. Can also be used as a rust inhibitor on new equipment... have you noticed that the heads of screws seem to be the first to rust? Coat them with DeOxit to prevent rust forming!

I'd like to thank my previous supplier of contact cleaner because they closed their nearby store and forced me to look for another supplier. I couldn't find one that could supply the same cleaner which I'd been using for 20+ years, but my attention was drawn to a note in a catalogue saying 'Deoxit D5 Spray... A must have for service technicians'. So I bought a bottle and was amazed at the results! I had persistent problems with a number of devices in my office and in my home for years and had tried everything using the old cleaner... but Deoxit D5 changed all that!

I first tried it on my mobile phone's battery terminals and charger connector as well as the SIM card contacts. All the problems I had with it disappeared including the 'no SIM card' message*. I then tried it on my cordless phone which was always playing up (not ringing or ringing when it shouldn't) by treating the cradle terminals and the AC adapter connector... problems solved. I also fixed an old power board with a 'dicky' switch... that's the great thing about DeoxIT - it acts as a lubricate as well! Can also be used to lubricate PCB edge connectors to make it easier to insert. I've also used it to lubricate power supply screw terminals and binding posts. i.e. it stops the squeaking! * There's another great thing about Deoxit... it can quickly show you where the problem lies! The SIM card problem kept returning so I pulled the mobile phone apart and cleaned out all the 'gunk' and applying DeOxit to all contacts and it hasn't played up since. My Nokia 3810 mobile worked for over 15 years and is still operational but no longer works on the 3G mobile network!

p.s. Because I would spray my old cleaner liberally (it evaporates away) it's taken me a while to learn to use only a small amount of DeOxit and to wipe away any excess. I found that it can cause problems on 'sensitive' analogue equipment! You can also flush DeOxit away using CRC 2016.

1. FIRST, you must really clean contacts and connectors...
WHY: Would you apply an enhancer or protectant on top of an oxidized/corroded surface? Would you apply gold plating over an oxidized copper based metal? Simple contact "cleaners" wash away dirt, dust, and grime, but prove ineffective at removing oxidation and surface sulfides. These tough contaminants actually attach to and become an integral part of the contact metal. This issue causes increased unnecessary service calls for covered warranty repairs that could have been prevented, translating into literally millions of dollars of lost revenue for service organizations. The only true method of eliminating oxidation and surface sulfides is by chemical action and reaction, and that's what puts CAIG DeOxit and DeOxit GOLD (ProGold) products in a class of their own.
2. Next, you want enhancement - to improve conductivity...
WHY: Why not improve performance, increase current flow, decrease heat and eliminate intermittents? DeOxit and DeOxit GOLD (ProGold) are designed to improve the flow of electricity between metal surfaces. These products are initially non-conductive liquids, when subjected to an electrical field, DeOxit and DeOxit GOLD (ProGold) promote current flow. No short circuits will occur. In both states, DeOxit and DeOxit GOLD (ProGold) have resistances high enough to prevent short circuits.

I can testify to the effective of DeOxit in reducing contact resistance! On a battery pack, with an initial short-circuit current of 8A, I applied DeOxit to all contacts (14 in total) and the short-circuit current INCREASED to 9A. Also on a power supply terminal connection drawing 60 Amps, I applied DeOxit and HALVED the voltage drop! Remember a small 50mV drop across a connection drawing 60 Amps, means 3 Watts of power is dissipated - heat dissipation accelerates oxidation of your terminals! e.g. Try it on your car or truck battery which draws over 200 Amps when you start the engine.

3. Finally, you need long-lasting protection - for improved reliability...
WHY: Once you have really cleaned a contact surface and enhanced its electrical properties, would you want to re-expose it to atmospheric contamination? i.e. humidity, salt, pollution, etc. DeOxit and DeOxit GOLD (ProGold) protect metal surfaces in two ways. First they mechanically bond, on a molecular level, to seal the metal surface. Second, the thin film moves as the contact is disturbed by vibration or another contact surface. In effect, the product(s) re-coat exposed surfaces. This is especially important on equipment subject to vibration. Greases, silicones, polymers and PPE's cannot reseal exposed surfaces. Once exposed or re-inserted they need to be re-applied.

4. CONCLUSION: When you want to do general cleaning and remove dust, dirt and grime, any contact cleaner will do. But when you need to cure contact related problems, and dramatically improve equipment performance, CHOOSE DeoxIT!

NOTE: DeoxIT does not necessarily remove any superficial discoloration (black tarnish) caused by oxidation or burn-in (on vacuum tube pins). This will, in no way adversely affect the performance of the equipment. DeoxIT and DeoxIT GOLD (ProGold) improves conductivity irregardless of this discoloration.

1. My most recent experience is in repairing and refurbishing electronic boards which were manufactured by Procon Technology 10, 20 even up to 30 years ago (these boards are used in automated lockers in amusement parks in Queensland, Australia and in ski resorts in New Zealand) and the 8-way DIP switches had become intermittent in operation and some were getting harder and harder to operate! Rather than go to the trouble of replacing the switches (which often results in PCB pads and tracks being damaged), I simply swamped the switches with DeOxit*, activated each switch numerous times and left them overnight. ALL are now working 100% as DeOxit also lubricated the switches! ONLY wish I'd known about DeOxit and applied it when I manufactured these boards, these problems could have been avoided. *remember GRAVITY is your friend and can be used to allow DeOxit to enter a device over time! If you can't use GRAVITY then you may need to open the device (if that's possible) or use the DeOxit aerosol spray to penetrate the device. NEW DISCOVERY! I just realised I can soak the top of the DIP switch with D100 and then use a spray "contact cleaner" to help the D100 penetrate the device... I can then get it to work WITHOUT leaving it overnight! A much quicker BUT less wasteful way to use DeOxit AND save time & money!
2. Rather than drag my soldering iron up into the ceiling space to replace a relay used to activate one bank of 240VAC flourescent lights in the garage when the automatic garage door was opened, I switched off power and removed the relay's cover and applied a drop of DeoxIT to the contacts and "Bob's your Uncle" the relay worked again without having to purchase a new relay and without having to desolder and re-solder a new relay into the circuit! Only wish I'd treated the relay when I installed it... it wouldn't have failed in the first place. Here's a video treating a relay... click here. NOTE: DeOxit DOES and SHOULD leave a residue... there is such DISINFORMATION on YouTube!
3. Five years ago an ADSL filter was installed in our ceiling space and connections were crimped*, over time we experienced intermittent failure (generally in summer) of the WiFi modem repeatedly resetting. Before calling our internet provider to see if there was a problem with the copperwire connection to the telephone exchange, I decided to check the filter. Applying some DeoxIT to the crimped connections fixed the problem! Again, I only wish I had applied DeOxit in the first place... using DeOxit is something that I automatically do now with all crimped connections! *or rather it was an IDC (Insulation Displacement Contact) or IPC (Insulation Piecing Contact) connection.
4. I picked up a Sanyo 17H-815 Transworld Radio on the side of the road. This 17-transistor, 6-band portable(?) radio was manufactured in the 1960's and worked OK on AM, only worked on FM if I held the button down and was intermittent in operation on the other bands. I used DeoxIT on all the switch contacts and on the potentiometers and it now works fine! A brilliant piece of Japanese technology restored to full operation.
5. One of the first jobs I used DeOxit was on a Kenwood HiFi System which had a scratchy volume control. Thinking that the potentiometer needed treatment, I opened the case of the main amplifier only to find that it was a DIGITAL volume control and clearly NOT your typical pot! I then treated all the rear connectors with DeoxIT, waited 2 minutes and switched it on... problem solved! NOT QUITE as there was a distortion in the sound output, so I flushed the excess amount of DeOxit using my old CRC contact cleaner spray and it then worked perfectly for many years.
6. One batch of double-sided PCB's (Printed Circuit Boards) we ordered had problems with solderability. It was taking 10 times longer to manually solder each pin! AND even then there was poor solder flow especially through the vias (we've discovered that this can cause PCB failure many years later, especially with rat and gecko urine/faeces being a problem where these boards were installed) hence all boards were treated with DeOxit applying it to a tissue and wiping each side of the board (great for PCB edge-connectors too) and then leaving it overnight and the solderability was no longer a serious problem!
7. A few years ago, our 15 year-old digital TV started "playing up". It appeared to be an antenna problem so I checked the antenna, cables and splitter (applying DeOxit, of course, to all connections), but that didn't solve the problem. It looked like a problem inside the TV... maybe even the "dreaded" Chinese electrolytic capacitor problem? Anyway, as a new TV consumed one third of the power (60W compared to 180W) I decided to upgrade to a bigger screen and more features and keep the old TV as a spare. When I did get around to examining the old TV, I found that all the capacitors were Japanese and absolutely fine. The problem? A corroded aerial connection inside the TV... so I applied DeoxIT and now it works fine!
8. Just repaired a Canon calculator that is 40 years old! This thing was my SmartPhone before we had SmartPhones (with only a scientific calculator, alarm clock and stop watch), so it has "sentimental value" and I still use it everyday. Anyway, I pulled it apart and cleaned the carbon film push-buttons using CRC (watch-out cold aerosol sprays will cause the rubber membrane to distort... just wait until it gets back to an even room temperature and it'll be fine) and the metal contacts on the PCB with Deoxit. Left it overnight, wiped the excess deoxit off and reassembled it... it's working perfectly again! If you get any Deoxit on the carbon film, JUST FLUSH IT OFF. Also treated our 5 year old digital room temperature controller the same (don't forget the contacts for the LCD display) and it's also restored to full operation... every time I pressed a Push Button the LCD display would disappear. Treating all gold-plated metal contacts on the PCB and increasing the pressure of the battery contacts fixed this!
9. Here's a time & money saving tip for you! We have a Daikin multi port Air Conditioning system and it had been issuing the "U2" Error Code for sometime. I finally got sick of resetting the unit (switching it off & on again) that I downloaded the SkyAir service manual and it was due to "insufficient supply voltage". Searching YouTube showed me that the most likely reason (forget replacing PCBs... check this FIRST) was that there was a loose mains terminal to the compressor unit (3MXS52LVMA). Sure enough, after switching off the power and treating all terminals (11 in total) with Deoxit and tightening them has finally fixed a problem that has plagued us for years... no more "U2".
10. Fixing a cruise control on a Subaru/Toyota? I have an old Subaru Legacy/Liberty with a lever-type cruise control mounted on the steering wheel (at 4 O'Clock) and I was having to press the "Set/Coast" multiple times before it would activate (i.e. it was "intermittent" in operation). Of course, I could have removed the airbag and proceeded to replace/repair the switch but I decided to see if I could get some DeOxit into switch mechanism without dismantling it. This is where I stupidly just sprayed some DeOxit Aerosol into the lever mechanism! At least it fixed the intermittent problem BUT the lever would get stuck in "Set". The problem it seems is that the aerosol caused dirt/dust to enter the switch mechanism causing it to jam... BEWARE. I decided that it's a good idea to CLEAN the mechanism first before using the tube of DeOxit above and let GRAVITY go to work and LUBRICATE the mechanism as well. So turn your steering wheel so the lever is in the down position, use a torch and small screwdriver and clean out any rubbish around the lever (hair, fluff etc). Then turn the wheel so the lever was in the top position (tip... never leave your car parked with the cruise lever at the top... that's how dust/dirt gets in there!) and apply many drops of Deoxit around the lever, activating it in all switch positions... and leave it overnight. Here's a video of the type of cruise control I'm talking about - click here. Which is similar to that on an old Toyota RAV4 - click here @0:45 you'll see all the dust/dirt in the lever mechanism!
11. How many more examples do you need? Anyway, the USA manufacturers claim that DeoxIT improves "conductivity" and so I decided to put this to the test... the first test I conducted (no pun intended) was a battery pack with 6 x AA cells with a total of 21 "physical" connections (which includes the riveted connections). I performed a short-circuit test (for one second only) on the NiMH cells and the reading was 8.5 Amps. Then I applied DeOxit to all 21 connections and the batteries, left it for two minutes and tested the battery pack again... 9 Amps short-circuit current was measured. Note: every other time I conduct this test, a second time, on a single AA cell... the current would be reduced! Another test was on binding posts of a 60 Amp desk-top power supply. Without DeOxit the voltage dropped 100mV at 60A across the terminal lugs whereas with DeOxit it was halved... around 50mV. Try it, even on NEW equipment, and you'll see that Deoxit does improve conductivity, thereby reducing heat (60A x 50mV = 3 Watts) and consequently reducing the instance of contact failure now and into the future!
