Back in the 60's Popular Mechanics, I believe it was, had an article
on stripping wood using TSP.
I tried it and it worked good.
You mix TSP, (sorry forgot ther mix ratio) with water, and heat to
below boiling. Wear protective gear!
Soak the part you want stripped for a few minutes or how long it
takes, and bruch away multi coats of paint.
I told a friend who restored old Victorian houses, and he tried it,
then had a shallow tank built with a burner below, to strip doors,
I wonder if you could soat a towel in it and hold against a verticle
moulding and apply heat, with an old iron or something else, and see
if it would work that way.
If you can find a box of TSP,(real TSP) try it on something small with
a lot of paint, and you will be amazed. DON"T leave things in very
long or it will soften the grain.
