Other FeaturesYour Remington beard trimmer requires very little maintenance throughout its life--simply keep it clean, charged and replace combs as necessary. Men with thicker hair or more frequent users may need to change components more often. Keep It Clean Keeping the trimmer clean and free of hairs will improve the quality of the trim. Many Remington trimmers come with cleaning brushes to brush off any build-up. Charge It Up By following the charging instructions in the product information leaflet, you are sure to maintain the trimmer's performance. Be sure to always completely dry both the trimmer and your hands before putting it on the charger.
