Between the car, house, garage, and maybe the office, we all tend to carry a bundle of keys. To make it easier to quickly find your most-used keys, paint both sides of the key head with brightly colored nail polish, using a different color for each key. The nail polish is extremely durable and lasts surprisingly longer than spray paint.
Color-Code Your Keys, and Two More Quick Tricks
A few quick tips to make your life easier with nail polish, lemon juice, and markers.
Identify Your Keys at a Glance
Erase Permanent Marker on a Dry Erase Board
Who hasn't accidentally written on a whiteboard with a permanent marker? It's easier to remove than you think: simply draw over the permanent marker with a dry erase marker, then wipe the marks away with an eraser or dry cloth. Your dry erase board will be good as new.
Remove Highlighter Stains
Ever wish you could remove highlighter marks from a book? Lemon juice fades highlighter enough to make it virtually undetectable. Cut a lemon in half, get some juice on a cotton swab, and run the swab over the highlighted text to watch the color fade.
