I always had commitment issues with my cutting boards.
After years of struggling with Sanitisers, soap, and water, I have given up. If I see a suspicious mold- like dot on my cutting board, I immediately throw it away.
My husband, who comes from a very environmental family has an issue with throwing away plastic.
The other day, while I was reading an article about the benefits of a wooden cutting board, he went out to our storage unit and dragged back a long piece of hardwood.
