What is the best contact cleaner?

I've used the following:

• real contact cleaner (didn't do so well as I reclled)
• WD-40 worked quite well but probably not good for higher voltage contacts; does leave a residue.
  
• silicon spray - mixed results (that stuff goes everywhere)
  
• carburetor cleaner (some leave no residue and others leave a mess so brand probably matters)
  
• 
  

Anyone have any experience and/or recommendations?

Servisol or Electrolube, here in the UK

I second the DeOxit ..... been using it for many years with excellent results. It really is superior stuff.

A good way to clean contacts is to use a simple rubber eraser. Those the kids use in school.

soda

 

I'm really concerned with multi-contact wafer switches like those buried on oscilloscopes!

I've been using Servisol Super40 (WD40 clone) for 20+ years now, far better than any contact or switch cleaner I've ever tried.

The whole point is that it leaves a residue, contact cleaner removes the switches (or potentiometers) original lubrication, the lubricating residue of WD40 replaces it.

Not to intentionally rain on what Nigel states, but to reaffirm using DeOxit, especially now that you mention that particular switch. You don't want to revisit that issue again. DeOxit will effectively deoxidize and leave a permanent oil/film on those contacts.... I've restored controls that were so bad I thought they would require replacement. DeOxit saved the day many times, especially on those specialty parts that are no longer available. It's thin enough that it will work its way into so called "sealed" controls. It also meets military spec for use underwater in subs and missles.... can't get much better than that! Well maybe they could give it a nice minty odor instead of the pungent smell it has!

I have had good success with WD-40 but I would like to try DeOxit. Seems to be a bit pricey! Who has the best price. The company website has it for $7.95 a can.

Dude,

Use your browser to search for best prices. We've already given you our recommendations, now we need to spend more time looking up prices for you?
And stay away from WD-40 ... that stuff is garbage and can cause flames depending what it's used on. It's only good for lubing creaky door hinges and removing adhesives residue. For heaven's sakes never ever use carburetor cleaner!!!!

I'm scratchin' "Mr. HiTech" off the list for Good Will Ambassador to Pennsylvania!
I can Google with the best of them; the problem is getting 10,000 hits and trying to go through each one. If someone has a reputable dealer that they have used and are happy with then I would appreciate a link. Otherwise you have the right to keep your mouth shut!

Only a complete moron would spray inflammable gas pressurised aerosols on to sparks - almost ANY aerosol is inflammable these days - use a little common sense.

WD40 is far better than most contact cleaners, I've never tried DeOxit, in fact I've never heard of it, but WD40 works perfectly so I see no reason to even try it (if I could find it).

You have the right to go ahead and do that. I'm not here under the advice of Mr. Dale Carnegie. But, I am here to officially state that within 30 seconds I saw that my Google browser showed the following primary suppliers: www.caig.com, www.partsexpress.com, www.radioshack.com, www.mcmelectronics.com. And just for kicks I entered best price DeoxIt into the browser and www.music123.com verified what may be the lowest price on-line. Oh, by the way, I have purchased from each and everyone of those listed businesses without any negatives.

Now that wasn't so difficult was it? Dare I ask for redemption? Not!

My friend's father sprayed WD-40 into a wall switch that operated a ceiling fan... it smoked and flamed up. Luckily it was contained within a metal work-box while he ran for the fire extinguisher. That old man sprayed WD-40 on everything around the home!

I know from personal experience that it works wonders removing calcium/lime deposits on plumbing and other kitchen/bathroom surfaces from hard water stains. Even the dedicated removers like CLR, Lime Away, etc. barely worked, but WD-40 made the task effortless!

To close with a funny story: I remember years ago when my fiancee' used the stuff to clean her car's interior. As I entered her car, I slid forward to the floor, off the slippery vinyl seat, wondering WTH?? Here she used WD-40 to clean the upholstery because the can states "cleans"!!!! I told her that if we were to go through with getting married, that she had to promise me that she'd never use WD-40 on any furniture ever again! We've been married for a long time and if I fell out of a chair it was from one-too-many beers!
