Is there a way to get onion smell out of my bamboo and wooden cutting boards?
Are you channeling your best self with this comment? (If you're not sure, check out our Code of Conduct.)
I've used the same wood cutting board for about 30 years. I keep a spray bottle of water with a bit of bleach in it and use it on the board after every time I cut something. No smell, no illnesses.
I use lemon juice, and about once a month I rub in lemon oil.
Scrub it down with coarse grain salt and white vinegar - the salt scours while the vinegar kills odour, and both disinfect (and are safe to eat!).
I also add a bit of lemon. This is also a great way to clean coffee makers.
Sorry ... Vinegar has a distinctive taste, residue. Lemon, not quite so.
Sprinkle the board with coarse salt. Cut a lemon in half & use the cut side to scrub the board.
Once clean & free of odor, oil the board with food grade mineral oil and/or beeswax. Don't use any oil you would use for cooking as it can go rancid in the board. You should be able to find food grade oil easily. Most kitchen stores carry it. A bottle costs about $5-7.00 and will last a long time. There are also products that mix oil with beeswax that work very well. Treespirit is a good brand.
Not only does it keep away odors, it protects & therefore lengthens the life of the board and makes it look good, too.

You can get food grade mineral oil at most drug stores. It's in the laxative section at walgreens.
By the way, you should use mineral oil on ALL your wooden tools, spoons, steak knives, salad bowls. They'll last for many years with proper care.
Mineral oil yes, prevents stinkiness from really setting in. Then my cleaner of choice is rubbing alcohol. Is does a great job of disinfecting and doesn't leave any sort of smell behind like vinegar can.
