Computer keyboards are magnets for dirt. One reason is that the keys acquire dirt from dirty fingertips. Another is that dust and food particles accumulate in the spaces between the keys. This accumulation can eventually damage the keyboard. One solution, in addition to being more careful, is to occasionally turn the keyboard upside down and tap lightly on the back of it. If this is done over a dark surface, sometimes an amazing number (and variety) of particles will suddenly appear on that surface. Dirt on the keytops themselves can sometimes be removed by rubbing them with a slightly damp cloth or paper towel. But it is important to not use so much water that some of it spills between the keys. For particularly dirty keys, it might be more effective to brush them lightly with an old toothbrush that has a small amount of fingernail polish remover on it. However, this should first be tested on a small section of a single key to make certain that it does not damage the keytops, including the lettering on them. Created September 30, 2006. |
