It's basically Lye. Sodium Hydroxide and a glycol carrier . Turns your Skin into Soap like Granny Clampett did with the cast iron wash pot on the Beverly Hillbillies using Lye and Fat.
Not something you would leave sitting on about anything for an extended time.
How I strip slot car bodies. Heavy duty Easy Off oven cleaner in a plastic container and dunk them for a day or so and removes any thing not contained in the body resin. If I'm not happy with the paint job or screw up
Something, toss it in the Tank and start over with a clean slate. Lye is the opposite end of the ph scale from Acid and just as deadly. We used both cleaning A/C condenser coils. Acid type will etch,brighten the soft metals but won't touch oils,grime and such whereas Alkaline will do both although not as bright on aluminum. Don't remember which one will turn aluminum black if a high magnesium cast like motorcycle cases and the like so be careful which you use on what. Pretty sure it was the Acid type because it came out first and a friend wanted his Honda case's " shiny " OOPPPS.
When cleaning Aluminum sheet,plate, I would use one or the other to determine what tone,light or dark, I wanted before clearing if it wasn't being polished.
