Is there a way to remove dried wax from wood or metal?
For a drip of candle wax on a wooden table or floor, put a paper towel over it, then run a warm iron over the towel. Move the towel to blot up the melting wax. You can also soften up the wax with a blow dryer and blot it the same way. This trick should work for metal surfaces as well, but may be more difficult if your metal surface is vertical. Scrape off as much as possible with a blunt, straight edge.
