You may not be rough with your drawers and cupboards, but you may well find yourself tightening certain pull screws once too often. Keep them in place by brushing a little clear polish on the screw threads, insert the screws and allow to dry before using again. This is also a great solution if you’ve been keeping a Phillips screwdriver in the kitchen for loose pot handles. You can also use clear nail polish to keep nuts on machine screws or bolts from coming loose, and if you need to take the nuts off, a twist with a wrench will break the seal.
