I just bought a dozen spray cans of 'Brake Parts Cleaner' to deflux circuit boards. It is a mix of alcohols. I paid US $1.99 per can, instead of the higher price for cans labeled 'Flux Remover'.

Thanks for the infornation. You clearly know more about this than I do. We were afraid to drink anything 190 proof or higher because of the potential benzene contamination. We had no idea what level it was.

I looked up the composition of a flux remover. It is ethanol with isopropanol and ethyl acetate. That ought to make a good board cleaner.

I remember when we cleaned boards with freon in an ultrasonic cleaner. That worked well and never left a residue.
