Is there a substitute for "Flux-0ff' spray?

[reiver]

I have a couple of amplifier audio boards that have some flux gunked up on them (too much soldering).

But noone in my area sells Flux-off anymore, including Radio Shack. Can I substitute another solvent like Brake-cleaner without destroying anything? I know most electrical parts are rated to take a variety of solvents.

Ideas?

Isopropanol works well, leaves no whitish residues, and is safe, even with sensitive parts such as PS capacitors.
You can find it in a spray form as a whiteboard cleaner.

I've been using lacquer thinner with good results for years.

Isopropyl (rubbing alcohol) is fine, and won't destroy plastics, especially polystyrene caps, like stronger solvents.

Yes, it is what a skunk uses! Nobody knows better how to say "Flux-0ff" than a skunk!

But seriously, I use a spritzer bottle with a plastic straw from a WD-40 can or similar hot glued to the nozzle and filled with 99% isopropyl alcohol from the drugstore and a nylon brush like a toothbrush. Saves a ton-o-money over the spray can products.

Thanks everyone, I'm glad I didn't waste money on mailordering some flux-off.

I have a bottle of 99% iso on my shelf, I know what I'm doing tonight....
