Aside from being hazardous to the health of the people who are exposed to it, the presence mold can cause extensive damage to the wood of bathroom cabinets. This is why you need to make sure that you are able to get rid of mold as soon as you see it. If you see some mold starting to grow on the surface of your bathroom cabinet, you can either try to clean the wood or sand the wood until the mold is gone.
If you want to try cleaning the wood, you can start by mixing a tablespoon of ammonia-free detergent with a cup of bleach and a gallon of warm water. You can then place this solution in a bucket and dip a scrub brush in it. Using the scrub brush, scrub the moldy surfaces with the solution and allow the solution to sit for around 15 minutes. Make sure that you are wearing rubber gloves while before doing this to protect your skin from the mold and the bleach solution. After 15 minutes, you can then wipe down the bathroom cabinets using a cloth that has been dipped in some water. This should rinse off the solution. Before closing the doors of the cabinet, make sure that you have allowed them to completely dry first. To prevent mold from growing on the surface of your wooden bathroom cabinets again, you can use a fan in the bathroom, especially when there is water in running, and make sure that your cabinets are regularly cleaned.
If you want to sand the wood, you can make use of a rough sand paper. After removing the mold, make use of a finer sandpaper to smoothen the surface. Again, make sure that you are wearing gloves as well as a face mask to protect yourself from the mold and from the dust that would result from the sanding. After sanding the wood, you can then make use of the same bleach and detergent solution that you would use if you would just be cleaning the surface to wash the wood. You can then scrub the surface and then rinse it with a wet piece of cloth. Allow the wood to dry before refinishing the surface using a varnish or a stain.
