JC- I just found the chore of obtaining a vessel large enough, and getting that much acetone, to be a nuisance. I may end up doing just that, though. The oven cleaner seems to have evened out the staining, but I have a feeling its leaving a black / gray color - not very desirable.
Round'- the first stock I sucked oil out of 35 years ago, I accomplished by setting it many nights in front of the family fireplace, and dabbing the "sweat" with a rag. It worked well and it one of my better accomplishments! That was before we even had a hair dryer or heat gun!
Beleg - does the acetone NOT eat right through the plastic bag? I have a wallpaper tray that is a perfect size, but I was sure the chemical would work through the plastic tray is seconds!
