2 glass and unfortunately 1 wooden. The wooden one is old and gross. DH is only allowed to use it when he's cooking for himself. His theory is that it absorbs the germs so it's better than glass. I hate the idea of wooden boards.

Wooden one: DH wipes it after using and puts it away. Otherwise it'll be thrown out.
Glass: Hot soapy water if I've been using it for meat or 'messy' stuff. If it's just toast or sandwiches then I just wipe it with a Pine-o-Cleen wipe.
