I bought a wooden board after I saw a TV prog about plastic harbouring germs. It advised to wash in ordinary washing up water and that's what I do. I hope that helps.
Some woods will taint food, so choose sycamore or beech, if you hav'nt bought one yet,as they will leave no odors.
I wash mine with the dishes etc, with an anti bacterial washing up liquid.
A good little nail brush is handy in keeping a wooden board clean. Scrub along the grain with hot water and rinse off, though if you use a chinese cleaver scub along the cuts as well.
Agree on keeping the bleach off, unless you like your poached chicken extra white.
No, hot water - as in boiling water, a good scrub down the grain and bingo. And you can have three boards, one for meat, one for dish and a veg/fruit one.
