Evelyn, I use nothing BUT QRB paint and varnish remover. We moved into an old farm house with beautiful wide trim and mop boards but long ago former owners had applied a cheap,dark varnish over the existing finish. To this day we cannot understand why. I have stripped 6 rooms in our house and have 2 more to go. It is a lot of work but QRB makes it easier. I Simply apply it, let it set and scrape off old finish. I use a green scratcher pad dipped in QRB to do the clean up on the wood. I wouldn't use any other product.
