It seems that I am the only one in the whole world who microwaves cutting boards and UV boards.
1. Wood boards - Depending on size of board and power of MW, less than a minute or you can start a fire.
2. Plastic boards - a wet towel on top and bottom then MW.
3. Wood or plastic, germicidal UV lights for a few minutes, if I have to cook for other people.
Interesting that microwave and UV lights are on the two extremes of the electromagnetic wave spectrum.
