Scratchy controls and brake cleaner

[Guest]

Archived from groups: rec.audio.pro (More info?)

While washing the car, I turned on the radio. The volume control was
scratchy so, rather than tracking water into the house to get my good
stuff, I picked up a can of brake cleaner (tetrachloroethylene sp?) and
shot it a couple of blasts. Worked fine.

Any long term ill effects from this?

Brake Cleaner is essentially paint thinner, its trick (what makes it great
for cleaning brakes) is the high pressure you get from the Can. So, i
would say you did nothing more than remove the lube from the pot.. You wont
find a can of brake cleaner near my gear, but when i'm doing brakes, sure,
Great stuff.

You may find you're self replacing that stereo or the pot, in time due to a
lack of lubrication. I guess with lower quality components, probably not
that much of a loss or overall damage, Especially a cheap car audio pot. But
I certainly wouldnt spray it into my A&H.

a better choice would have been a silicon based tech spray which cleans,
deoxidizes and lubricates. i prefer Caig Deoxit but most other brands will
do in a pinch.

i hear that brake cleaner spray makes a great wasp killer.

It's not plastic friendly.... any plastic that got overspray may fail.

You must have a pretty old car. The last three cars I've owned (over
more than 25 years) have had digital volume controls. They even have
latency so I know they're real.

I have used 80% isopropyl + 20% WD40 mix with much success.... cleans,
evaporates and lubes... try it on some 'kill or cure' pots

Ah, finally we get around to the WD40. How do you mix them and then
spray the mix? Or do you load the mixture into a syringe and squirt it
in to the pot?

And is that 80% of 95%, 90%, or 70% isopropyl alcohol?

Brake cleaner is mostly MEK. It will melt plastic pots completely.
It might be okay for carbon pots but I wouldn't bet on it.

Yup, an '86 and not a great radio then. Still working OK today, so I hope
nothing important got melted.

Actually, I kinda hope it does. Give me an excuse to replace it.

Syringe.. give it a good shake then squirt...

99% IPA

I would not use it for anything rare or valuable but it does work as a 'kill
or cure' way of cleaning crackly pots.
