Tar paper is petroleum based. So, your removal solvent will
need to be petroleum based. I'd be tempted to haul the saw
outdoors. Lay paper towels over the saw top, and soak the
paper towels in diesel fuel, or kerosene. Cover the wet
towels in aluminum foil, and wait over night. Remove the
foil, and see if the grime is any looser.

The other zany thing comes to mind is Easy Off oven cleaner.
Which is strongly hydroxide. Sometimes that will change
grease to soap, which rinses off more easily.

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 have tried:

Scotch Brite
Steel wool
Sand paper

in combinations with:

WD40
Goof off
Acetone
dishwasher soap
baking soda
mineral spirits

Nothing works!

Any further ideas would be appreciated!

Thanks!

Sam
