Odor Eraser - Stainless Steel

does this work for my bamboo cutting board - to remove the stink of onions off it?

I think it’s just for hands. However, I also have a bamboo cutting board and what I do for that is rinse immediately after use, and add baking soda to the scrub brush when I wash it. The grittiness of the baking soda seems to do a good job of getting into the cutting board and cleaning up all the onion juice. Hope that helps!
