Floor finishes and certain chemicals in wood oxidize and are affected by ultra violet light sources. This may cause the wood and finish to change color and develop a patina or aged appearance. To avoid uneven appearance, move area rugs occasionally and drape or shade large windows.
Engine grime can be difficult to wash off of your hands. If you don’t have a hand cleaner handy, your kitchen cupboard probably contains a solution. Reach for either a vegetable or olive cooking oil and spread a dab over your hands. Rub your hands together, then wipe off with a paper towel. Cooking oils will also help remove oil-based paint from hands and arms.
