I had my brother-in-law (cabinetmaker) build one for me 30"x45" and
router a blood ring all the way around. He then cut a 3"x8" hole at one
in (where the blood ring empties into) for a drop into the waste
container. I just scrape clean with a large knife, wash with dishsoap
and scrubby, and apply vinegar wash. I could probably sanitize a little
better, but I don't worry about every little microscopic germ. I plan
on doing the rest of the countertops in butcher block. Besides
function, it looks great.
