But here's a likely solution!
This flexible computer companion, available in blue or black, can't be hurt by drips, drizzles or spills. Plus, with its completely enclosed keys, you won't have to worry about crumbs finding their way into hard-to-reach crevices. When you do need to clean the keyboard, use any disinfectant or simply soap and water.
Available at AliMed, the cost is a cool $40.
