Contact cleaner advice needed

[geordiejohn]

I have an old sound mixer that has not been used in years, when I went to hook it up to my amp for karaoke all the pots and switches were very noisy, the mixer is unusable in this condition.

I have stripped the main board out and was hoping to spray contact cleaner into all the pots and switches, is this likely to fix them? Can anyone recommend a spray, there are so many to choose from?

I haven't used contact cleaner in years, but always found Electrolube as good as any.

I have some switch cleaner from Maplins, cleaned all my pots on my old Sansui amp, not a crackle to be heard.

I use Servisol switch cleaner and lubricant (red label) Servisol Super 10 Switch & Contact Cleaner Solvent Spray - 200ml

I noticed when looking for this that there's also a Servisol cleaner (no lubricant) with yellow label http://www.ebay.co.uk/itm/Servisol-...734674?hash=item5d561d88d2:g:ynkAAOSwqu9U9s9E which might be better if the lubricant left behind is not required.

As an aside I've had my can of cleaner for decades, from when they were located in Hoylake in fact.

Thanks for the quick advice, there is a maplins on the way to work I can call in at. Some of the pots are hidden, is there a usually hole in them to get the spray in?

If there isnt just dribble some down the spindle or in through the solder tags area.

Dont use wd40 - its supposed to dissolve the carbon on the pot surfaces.

An ample dose of 'evaporating cleaner' aka 'contact clean', move the part a dozen times while the stuff is in there, then a minimal dose of 'lubricating cleaner' aka 'contact protect'. As to which brand, no idea what's available around the world. Certainly not use wd40 and those kinds of products.

Am using a needle to get the stuff exactly where it should go, see picture.

Just remembered the name of the stuff I occasionally use at work - Fospro

We use to use this stuff called "Tweek" back in the 70's, but it was tricky stuff.

I now use this stuff.
