When it comes to removing excess beard oil or balm from a wooden beard comb, a simple wipe with a soft, dry cloth is generally your best bet. However, if you've recently tried a new beard conditioning product and dislike its smell (and the odor left lingering on your comb), a quick rinse in soapy water might be necessary. Keep in mind that repeated exposure to water can severely damage a wooden beard comb, so be sure to minimize exposure to water and dry your comb thoroughly afterward.
