Generally the male plugs don't need cleaned, there are exceptions - such as some cheap imported plugs or the old military brass plugs, which you shouldn't be using anyway - but for the most part they usually are not the problem when you have poor contact problems. I've got some Switchcraft and George L's that are at least 15 years old and they have never been "cleaned".

The female jack's sometimes get to the point they don't make good contact, however, many times they have a second "closed" contact (makes contact when a male plug has not been inserted) and that's where a lot of the jack problems are.

Most good quality CONTACT cleaners will work well. Generally the stuff you buy will work for both contacts and for pots (controls).

The best way is to have the unit apart and then pry the jack apart so you can get contact cleaner on the "closed' contact. However, that's usually not an option when you're cleaning so just spray some cleaner into the jack and then run the male plug in and out several times. That will usually take care of a "dirty" jack, except in severe condtions. Sometimes just pluggng in a male plug (in and out several times) is all that's necessary to fix a flakey jack.

As far as brand names, there are many good cleaners available from Chemtronics or GC Electronics, but these are usually only available from Electronics Parts Distributors. The contact cleaner that Radio Shack sells ( 64-4315) will usually work satisfactory for most applications.

The product that I swear by for conductivity issues is called DeoxIT and is available from CAIG Laboratories (www.caig.com). This product can be used on male and female connectors and on switches and pots(if you have the skills to disassemble and reassemble them). They also offer a product called ProGold for gold plated contacts, and they offer a variety of other surface treatments. These products are available in a number of applicator styles from liquids to pastes to sprays to wipes. My favorite is a pen applicator (nerd-pack special). Treatment with these products is good for the long haul, and retreatments are seldom needed except in an adverse environment. I'm not sure if the road qualifies as adverse, but maybe so. I do not work for the Caig folks, but I like their products.

For scratchy pots, WD40 works really well because it also lubricates and gives the pot a nice smooth feel. Just make sure to use this without power applied, as should be the case with any cleaner because they may be conductive, and may short something out if you're not careful. That is why it is best to make sure the unit is unplugged.

I would caution against WD-40. I've repaired some units (replaced pots, etc.) that WD40 was used on.

I use a spray that I got at an electronics store called cramolyn. It costs $12. for a little spray can, but it has saved me a fortune in repairs. It is great for pots, switches, jacks, etc. It has a little straw like WD-40, that will shoot the stuff just about anywhere. It penetrates into things through the smallest of openings.

Cramolin is the name of an older product by CAIG Laborotories. It came in two colors, red and blue. Both have been replaced by more environmentally-friendly products, the red by DeoxIT and the blue by PreservIT. All the above mentioned products seem to work equally well in my experience.

Hey Vic & Mike,can I buy the DeoxIT at most electronics stores or do I have to order it from Caig Lab.?

And thanks to all for you advice.

Stew-Mac ( www.stewmac.com ) 800 848-2273 has a 5 oz. spray can for $10.49 but they have a minimum order of $30. I remember that someone posted a better price somewhere but I can't recall who/where.
