TO TAKE OFF THE PAINT.
If you have an old, roughly painted door to cut down for a fine job, don’t fool away your time, and fill your nose with dust, trying to do it with dry sandpaper, but take the door off its hinges, lay it flat on horses, and keep the surface under your sandpaper wet with benzine, and you can do in an hour what would otherwise take half a day. The benzine softens the paint, and keeps the paper from gumming up. If it is not practicable to take the door off the hinges, put your benzine in a small spring-bottomed oil can and squirt it on the work as needed to keep the paper clear of paint and make it cut fast. Wipe off the loose paint with rags. It works equally well on old varnish. Try it once on an old carriage body.
If the old paint is extra hard use a mixture in equal parts of benzine and ammonia.
