Paint stripper combined with old paint or varnish makes a sticky goo that can be tough to remove from a scraper or a putty knife. To make an easy job of it, I cut a straight slit about 2 in. long in a large tin can. Then I slide the blade of the knife into the slit close to where it joins the handle. When I pull the blade out, the old finish falls into the can, ready for disposal.
