Thank you all! I think that Chilean "bencina blanca" is the same as white spirit. And about the hands thing, i'm a paramedic so my hands must be always clean, that's why i work my bikes using gloves. I used to use latex gloves but many products do some kind of chemical damage to the material and they tend to break easily, my solution was to use nitrile exam gloves. They are resistant to chemical and mechanical damage and you get a really good feel, they are not unconfortable as vinyl gloves are.

Thank you!
