I found out today that my nice bamboo cutting board took a run through the dishwasher. The "wood" looked pretty much dried out and felt rough. Is there anything I should do? It's a small bamboo board that I use mainly for cutting limes for drinks...so its not a huge loss but it had quickly become one of my favorite kitchen items. Currently I have it sitting in a pool of mineral oil, hoping I can soak some moisture back into it. Maybe I will have to sand it smooth again afterwards (the 2 edges where the bamboo fibers come to an end got especially rough feeling).
