Back in the 60's, I believe it was Popular Mechanics, printed an
article on using TSP for stripping paint. Can't remember the mix
ratio, but after mixing, you heated the mixture, to a below boiling
temp. and soak the item to be stripped. In the 70's I tried it and It
worked like a charm.
I told a neighbor, who had a business restoring older houses. He had a
lot of shutters and doors to strip. He tried it and it worked so good,
he had a shallow tank built, with propane burners below it, to heat
the solution. I was the Hero!
It doesn't take long, and if you leave the item in too long, the wood
will get soft. Don't ask how I know!
Soak a bit and hit it with a stiff brush, and brush away 50 years of
