I think it's hilarious that people are giving their PCBs baths. From the age of "don't eat or drink near a computer" to "first, get some dish soap, and a bucket of nice warm water..."

Only thing that sucks is paper labels won't survive that.

For cards that are really grimy, I just use dish soap and water and scrub them with a brush.

I then thoroughly rinse the soap off with clean water and then dry using an air compressor. Using an air compressor for drying ensures water is cleared out from all the crevasses and there won't be any mineral residue from evaporating water.

THIS, simply, awesome result.
