Don't open the attached picture if you are easily shocked or distressed.

This is what happened to my subwoofer amp when a carpet shampooer I was hauling in the back of my station wagon leaked carpet shampoo that worked its way through the floorboards and onto the amplifier.

Surprisingly, I was able to remove all traces of the damage with Q-tips and some household cleaner. When I was done, it looked just like new.

Of course, it still didn't work.

Blaupunkt fixed it for a flat fee of about $110 plus shipping.
