Stripper with Methylene Chloride is still manufactured here. The EPA ruled it could no longer be sold retail. i.e. Home Depot etc. It can be gotten wholesale if your a direct user.
I restore antique mahogany runabouts. I use about 50 gallons of stripper every couple of years. I just bought a 50 gallon barrel of stripper with Methylene Chloride in it.
If you need some find a professional furniture restorer, boat restorer or old house restorer. They will probably have some you could buy from them.
