I don't cut meat, or anything for that matter, on it. It's used as extra counter space when I cook, and it inevitably gets various drips, spills and crumbs. Thanks in advance for the cleaning tips!
I use bleach to clean mine. Simply sponge it off with the bleach and water solution. Finish off by wiping it again with a clean sponge, no bleach this time, let it dry before putting it away. If bleach bothers you, try to clean it with plain vinegar.
