I used a cardboard the thickness of cereal boxes to make a stencil for cutting clear plastic in to a rectangle shape slightly larger than that of keyboard and made numerous pre-cut clear plastic protectors to last through out the year. Be sure not to cover any ventilation openings. By using a small square of transparent scotch tape on each of the 4 corners, this keeps it in place. Each time I clean and replace the protector, I use rubbing alcohol placed onto the cleaning linen before wiping it down. The alcohol cleans food, oils, and tape adhesive off very nicely. Do not apply alcohol directly to the laptop. Dyg
