I don't use the wooden one often because it doesn't fit in the washing machine but DH does.
o.O

We have about 10. Each colour coded. Each for different things. I have thin flimsy ones. I have thick ones. (all plastic) and I have about 3 wooden boards but they are used for bread, as servers of food or as trivets.

We have blue for poultry. Red for red meat. Little Yellow for Cheese/Butter/Dairy. A different type of blue one for Fish. Big Yellow for sandwiches. Big White for sandwiches. Green for Vegetables. Little White for Onions.

I bleach all the plastic ones (food safe ratio). And only was the wooden ones with cold water and dishwashing liquid. Then occasionally I'll scrub them with lemon and salt and put them out in the sun.
