MG Chemicals4050-1L Safety Wash Electronics Liquid Cleaner, 1 Liter Bottle

Way easier to use and cheaper than an aerosol electronics cleaner. I use it on the tires of my RC cars.

Best stuff I've found for cleaning a gunky circuit board, usually during a repair or service. Use with good ventilation. I put it in a spray bottle. Hold the board over a container and spray away, the gunk just melts away and flows off.

I thought it is a cleaner but I am still using the alcohol to clean it. I think I am just making myself more work to clean up the boards.

MG Chemicals makes a number of formulations composed of various proportions of ethanol, isopropanol and ethyl acetate. For my hobby electronics workshop I have settled on this variant to serve in multiple roles: flux remover, adhesive remover, general-purpose residue-free cleanser, etc. Do note that it is flammable and that it evaporates fairly readily from containers that are not fully sealed.

After PC Board component replacement I clean off the flux residue using this solvent. The process is simple: Dip toothbrush into solvent, lightly scrub, then blot the wet area with a clean paper towel. Works great!Be sure to use in a well ventilated area.

I use this to soak water damaged phones that have a lot of plastic pieces inside of them. It works great and with a little help from a toothbrush all the corrosion disappears. Can't beat the price either.
