Whitening Yellowed Keys
Many older keyboard keys will yellow with age, and there is a way to restore those pearly whites! This method will either get your keys perfectly white again, or at worst, will make a big step in the right direction - it all depends on the type of plastic the manufacturer used. But in any case, it will be a big improvement.
First, you will need to find the secret sauce. You will want a peroxide-based cream that is used for hair coloring; a couple of examples are shown at left. We have found what we need at Sally Beauty Supply, and at wholesalers that supply to salons. You do NOT want straight hydrogen peroxide liquid - it needs to be a cream that can be brushed onto the keys, and will stay there until removed.
Once you have the cream, wait for a sunny day, and then remove all of the white keys from your keybed (the black keys can stay in place). Depending on which keyboard you have, this might be an easy thing, or it could be very tedious. Just make sure that you can put everything back where it goes in the end! Snapping a few quick photos could be very helpful.
The sun is important - it is needed to react with the chemicals to work the magic, so you may as well keep your keyboard together until the weather is cooperating.
The idea is to brush the cream onto the tops of the keys, and leave them in the sunlight for a full day. But since you don't want the cream to evaporate, put the keys inside a sealing plastic bag, or a tub with a clear lid. After a day of sunbathing, rinse the keys off with water, and they should look much nicer than when you started!
