Circuitboard cleaning

mike49504 · 8th July 2011, 06:32 AM

Im working on an amp that has tons of corrosion on the board.

The power supply section is where its at the output side of the board looks fine..

Wondering if anyone knows what will take this off the board since acetone doesnt touch it?

I have used brake clean and compressed air alot of times without any issues. You can also use a small wire brush to get the bigger stuff off first.

If the components aren't badly damaged/corroded, you can use a fine or soft (brass) wire brush to clean corrosion from the solder side of the board. A pressure washer also does a pretty good job on some amps.

i used denatured alcohol and some q-tips to clean some minor corrosion off a rockford amp i'm working on. seemed to work quite well
