To get the most out of your natural wood soap dish rotate between two dishes. Use one dish for two weeks, wipe it clean and let it dry completely and switch to the second dish while the first one rests. This rotation helps prevent mold, mildew, and soap scum preserving both your soap and your soap dish.  If using just one soap dish- every three weeks, wipe it clean and let it dry overnight. Return to use the following day.
