If your electric trimmer is your go-to grooming essential—maintaining that perfect stubble week in and week out—it’s common to rely on it again and again without thinking twice about cleaning it. Sure, you give it a tap to get rid of the built up hair, but when was the last time you cleaned it properly? Just like your favorite sneakers or a cast iron skillet, a quality beard trimmer performs best with proper beard trimmer maintenance.

If you don’t properly maintain that trimmer, it slowly becomes a bacterial hotspot and its performance starts to deteriorate. And we don’t think you want either of those to happen. Ask any barber and they’ll tell you that you should be regularly cleaning your shavers. So whether you’re edging a stubble fade or keeping your beard lineup sharp, regular maintenance ensures your trimmer stays powerful, precise, and free of dangerous grime. Here’s how to keep it running like new. Don’t worry, it seriously takes just a few minutes. And you’ll notice a difference right away.

Your Trimmer Maintenance Plan

1

Brush It Off

Use a small cleaning brush to sweep away loose hairs from the trimmer blades. This is the simplest way to prevent hair and dead skin from clogging up the mechanism. Just remove any guards, give it a tap and brush it clean. If you lost that tiny brush (hey, it happens), you can buy a replacement or simply use a cheap toothbrush. For a deeper clean, use a damp cloth to wipe down the handle and outer casing.

Wash (If Waterproof)

This isn’t necessary, but if you have sensitive skin or suffer from acne, a super clean trimmer can help minimize irritation. Check to make sure your trimmer is washable or waterproof and then rinse the blade head under warm water. You can use a drop of mild soap to remove oils and skin residue. Or wipe the blade head down with a cloth dipped in isopropyl alcohol to help sanitize the blades. Rinse thoroughly and let everything air dry completely before reassembling to prevent rusting.

Oil the Blades

This is a step you might’ve noticed your barber doing with his trimmer. A few drops or a spritz of oil on the blades will ensure it runs smoothly the next time you power it up. Not only does this make for a better grooming experience by reducing friction, it prolongs your trimmer’s life. If your device didn’t come with oil (or you already threw that tiny bottle out), there are options the pros use that are readily available. Most barbers use the Andis Cool Care Plus spray because it not only lubricates and cleans, but disinfects the blades, too.

Charge It

Most trimmers now have rechargeable lithium ion batteries. Let it fully drain before recharging and avoid overcharging by unplugging it once it’s full. This helps maintain the battery’s lifespan and keeps your trimmer working at full power.

5

Store It Properly

If you’re guilty of leaving your electric trimmer lying next to the bathroom sink, or even if you prop it up in the stand that it came with, you’ll be disappointed to hear that leaving your trimmer exposed to moisture and dust defeats the purpose of cleaning it completely. Proper storage means keeping your trimmer in a clean, dry place. Many come with a pouch or case—use it.

How Often Should You Clean?

Get into the habit of cleaning your electric trimmer regularly but how often depends on how frequently it’s used. If your hair grows quickly, you’ll likely have to clean your trimmer more often. Barbers typically recommend cleaning your shaver after each use, but most of us can get away with waiting until every third or fourth shave. Once a month is certainly a good habit.
