Just a few suggestions (learned the hard way):
- Don't use 150 grit, it's way too coarse, just as Andy said. I use
'steel wool', the fine variety sold for cleaning surfaces. If not
available, go for at least 300 or 400 grit. Unlike Andy, I never had
problems with Acetone, but I guess after the thorough cleaning with steel
wool, there wouldn't be any grease anyway.
- I've never seen mentioned that you should lay the board on an
insulating layer, but it _is_ needed. I use a newspaper (at least 10
pages). If no insulating is present, it's quite possible that heat is
drained from the board on several spots.
