I've recently had some doors acid dipped, but one of them has this
yukky brown paint/varnish stuff on one side which hasn't been removed
and I can't shift.
Is my only option to sand it off, or are there any good products for
removing it from the wood?
Nitromors - follow instructions to the letter for best results.
Dipping it should have shifted it.
Do your dipping elsewhere in future.
If the doors are old you will probably want to retain the patina, so don't

Tried nitromors, but it's not like removing paint - it's like some
coating nightmare from a cheap B-movie. The acid removed all the other
door' paint no problem. It's just this one type of varnish (dunno if
it's polyurethane in fact - just some sticky, brown rubbery awfulness).
Nitromors do, at least, two varieties- one of paint and another for varnish.
I had a similar problem, 'ordinary' Nitormors wouldn't shift the stuff, so I
went to a Paint Merchant and told them of the problem. They sold me a can of
the 'Varnish remover' which worked 'just like it says on the can'.
There are 2 types of commercial stripping tanks, one uses caustic soda
(not acid) and the other a methylene chloride type stripper. The former
will not touch polyurethane, but this is normally quite easy to sand off
because it doesn't gum up the abrasive. If it's as sticky as described,
it probably isn't urethane, and stripper and coarse wire wool is the
If it was a caustic dip, and you do get it off, you'll probably end up
with a patch that's paler than the rest. Treating this with caustic or
washing soda should tone the colour in
