I have an old (80yrs) porcelan tub that had some paint brushes laid in
it.. now there's some colors in the bottom of the tub  that I can't
seem to erase. I tried bleach and Oxy with no luck ...what can I do to
get the color up from insdie the porcelean?

thanks,
Eric

Eric,

If the finish has worn off the tub and the paint is embedded in
the clay, it may be very difficult to remove.  The first things to
try would be paint remover or stripper.  Here's a suggestion from
Pat Strong:

"A paste of paint stripper shouldn't hurt porcelain.  Try that.
Let it sit under plastic wrap so it really saturates overnight."
