Glue a magnet to the bottom of the hammer so you don't have to hold nails in your mouth while hanging pictures - (or for other projects. If the bottom of the hammer doesn't work out, a magnet on a clip to a belt would work too - JD)
Clean your microwave: Put a microwave safe bowl in the microwave, fill it with water, add a dash of vinegar & put it on for 5 minutes. The steam will soften up all the gunk & absorb the smells. Let it sit to let the steam penetrate.
