For removing lacquer that someone had painted on a brass case I had a while ago I used Trimite industrial paint thinners that I got from the workshop at school. I have since left school and don't know where I would get any more of this stuff as I think they only sell it to industrial users. I have never found anything better at removing lacquer, just soak the item in this stuff overnight and the lacquer can be wiped off. That No. 101 fuse in my other thread has been lacquered, which I would like to remove.
