My favorite has been Strip-eze. Unfortunately it does contain methylene chloride (a carcinogen) but I have found that it works really well.
Put it on, let it sit, scrape the residue off with a putty knife and wipe the stuff on newspaper. Then take denatured alcohol and wipe down the residue left on the wood using paper towels. I've not had much of an issue with the wood grain being raised with this method.
If the wood had a poly coat on it before it was painted that will help the paint to be stripped clean. Otherwise the paint may get into the pores of the wood and be hard to totally remove. Watch out for lead in paint-you don't want to sand that or the wood because lead from the paint can "leach" into the wood.
You can do the doors outside (out of the sun). Use a respirator with filters for chemicals if you work indoors and ventilate.
My Peel Away experience - ugh! I sent away for something called soy gel but haven't used it yet. I have used 5F5 but didn't like it as much as the Strip-eze. Safer Stripper-not as effective as Strip-eze.
Oh, don't leave the newspaper with the stripper and paint around outside. I did one time. Yellow jackets went into the newspaper after the stripper, got wrapped up in it and when my partner went to throw it out was swarmed and stung many, many, many times. email@example.com
