Some of the purple cleaners are LYE based, be vrey careful about that. Even diluted, lye is caustic and may remove paint and varnish and soften or discolor fiberglass if it is not neutralized (dilute acid washed) when you are done with it.
A friend of mine got too enthusiastic, I believe with the original Castrol purple cleaner, and years ago took the varnish off his kitchen cabinets. "OOpsie."
Steam is great, but for some of us it is impossible to locate or rent a steam genny, you need to be in farm country to find them!
