Hi,

I'm rehabbing an old craftsman saw which has never been used but sat in
a garage for 20+ years. The tar paper had completely rusted into the
surfaces. I have cleaned it up substantially but I just can't seem to
lift the remaining grime off of it. The funny thing is that the grime
seems to move around the saw (for example if I rub it with my finger),
but it's just too sticky to come up. Here are two pictures:

I can't tell anything from the pictures-- but if your finger 'moves it
around' - try a Magic Eraser. [follow the directions- they are to be
used dry]

Actually- have you tried all your abrasives dry-- or just with
solvents. Sometimes dry is better.
