By now we all know of the practice among keyboard cognoscenti to wash certain keyboards in the dishwasher.
I recently decided my gel mousepads were so dusty (I live in a rocky, mountainous desert area and am also a snuff taker) that I had to try this. Someone should pay me to torture test sealed equipment. My office is a total mess within a day of a heroic cleaning.
Ok so I actually threw my gel mousepads into the washing machine with a cool, short wash and a little laundry soap.
Excellent, they come out better than new. Amazingly they even stick to my desk and carts like before. However, after a couple of weeks they are back to their old selfs. I can see this will have to be a bi-monthly ritual.
This is a lot safer and cheaper than washing your keyboard! The cleansing effect will probably last a lot longer for you than me.
