Back when I was a bigger idiot, my Mini was laid up for about 18 months........under a Plum Tree. Not ideal, I know. After that it was garaged. Fast forward a few years and I'm recommissioning her, but the paintwork is coated in very hard to shift sap. It's all over the shop! Apart from that, the paint is in very good condition.
I've washed her several times, snow foamed, etc, but can't shift it.
Would I be completely off my rocker to use a Steam Cleaner? There doesn't seen to be a great deal of info online about it.
If I were to use one, would I use the Mitt, or just blast and wipe with a cloth?
Opinions / experiences, please.
