Single-use alcohol swabs are good for more than just cleaning minor cuts. In the shop, these inexpensive spill-proof pads are useful for erasing smudges and pencil marks, stripping the adhesive off sanding plates, and removing pitch from tools (especially thickness-planer feed rollers). Denatured alcohol won’t stain or raise wood grain and, compared to most other solvents, is safe to handle, as long as you follow the manufacturer’s safety precautions.
