The most important part of a ceiling fan is its motor. High-end brands usually have the most energy-efficient, well-designed motors, with die cast motor housings. Don't buy a multi-speed fan with only one capacitor inside its motor. A quality fan able to handle three speeds should have at least three capacitors.
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.
