I have a Boos Block cutting board (see link below - I have one of the chop-n-slice reversible numbers) that has - on one side - developed a nasty dark stain on the surface and a noticeable food stink. Mostly, it smells of onions and garlic with some rot thrown in. This odor will transfer to anything that is cut on the board.
I'm not really sure how this started, but I think that some moisture got stuck between the board and the counter and went unnoticed for a few weeks. I noticed the dark spot when I flipped it over. I assume the stink is somehow associated.
I've tried cleaning this in very hot water with soap to no avail; the dark stain remains as does the stink. I've also tried some gentle household cleaner on it (Ecover) but don't think I should try anything that is much harsher for fear of further damage.
Does anyone have any suggestions to how I can restore my once beautiful cutting board to its former stink-free glory?
Thanks in advance!
