How to disinfect hair clippers and blades

Clean clipper blades and trimmers: Why hygiene matters

Hair clippers and trimmers are used close to the skin, often around sensitive areas such as the neckline, jaw, nose, ears and scalp. During use, they can collect:

• Short hair clippings
• Skin flakes
• Natural oils
• Sweat
• Shaving gel
• Styling product residue
• Bacteria from the skin surface

If these are left to build up, the tool may become less effective. Blades can feel dull, motors may have to work harder, and guards can drag through the hair instead of moving cleanly.

Learning how to clean hair trimmer parts properly helps your grooming tools cut more evenly, look fresher and last longer. It also reduces the risk of transferring grime back onto your skin during your next trim.

How to clean clippers at home

The exact method depends on your preferred grooming tool, so always check the care instructions for your model first. However, the following routine works for most standard clippers.

• Step 1: Turn off and unplug the tool

Always switch the device off before cleaning. If it is corded, unplug it. If it is rechargeable, make sure it is not connected to a charger.

• Step 2: Remove guards and attachments

Take off clipper guards, combs, detail heads or trimming attachments. Cleaning each part separately helps you reach trapped hair and product build-up more easily. This is also the best point to focus on how to clean clipper guards, as removing them first makes it easier to brush out hair from the grooves and rinse them if they are water-safe.

• Step 3: Brush away loose hair

Use the small cleaning brush that came with your tool, or a clean, soft brush, to sweep hair away from the blade, attachment points and guard grooves.

If you are wondering how to clean hair out of clippers, you’ll want to tilt the clipper downwards and brush away from the blade opening. This will cause loose hair to fall out rather than be brushed deeper into the tool.

• Step 4: Remove the cutter (if your model allows it)

Some clippers have removable cutters or blade heads. If you are learning how to clean clipper blades at home, this step is especially useful because it lets you brush away hair and build-up from behind the blade area. For example, the Philips Hairclipper Series 9000 comes with three detachable clippers for easier cleaning. This model also needs no oil, helping keep maintenance simple and long-lasting.

If your cutter can be removed, detach it carefully and brush behind the blade area. Do not force any parts that are not designed to come off.

• Step 5: Wash water-safe parts

If your grooming tool or attachments are waterproof, rinse the suitable parts under running water. For instance, the Philips All-in-one Trimmer 9000 Series is 100% showerproof, so it can be rinsed more easily as part of your cleaning routine.

This is also useful if you want to know how to clean clippers in water, but the key rule is simple: only rinse parts that are designed to be water-safe. You should be able to find out what is and isn’t by reading your device’s manufacturer’s guide.

• Step 6: Dry everything fully

Shake off excess water and dry parts with a clean towel. Leave attachments and blade heads to air dry completely before reassembling or storing. Moisture left inside a tool can cause odour, corrosion or performance issues, so patience is important when learning the best way to clean clippers.

How to disinfect hair clippers

Cleaning removes visible debris, while disinfecting helps reduce bacteria on the blade surface. You can disinfect clipper blades at home after brushing and drying them.

To clean clipper blades and disinfect them:

• Brush away all visible hair.
• Remove the blade or cutter if your model allows it.
• Make sure the blade is dry.
• Apply a suitable clipper disinfectant spray, designed to sanitise and clean clipper blades.
• Let it sit for the recommended contact time (read the manufacturer’s guide for more information).
• Wipe away excess if required.

Finally, you can store the clipper in a clean, dry place, ready for its next use.

How to clean a hair trimmer

If you are asking, “How to clean my beard trimmer” the process is similar to cleaning clippers. Beard trimmers often collect more oil, balm and skincare residue, so it is important to take care to properly clean and disinfect.

After trimming your beard:

• Remove the guard.
• Brush hair from the blade and body using a soft brush.
• Rinse washable heads if allowed.
• Disinfect the blade area using a clipper disinfectant spray.
• Let all parts dry before reattaching.

Beard trimmers used around the mouth and jaw should be cleaned often because they come into contact with facial oils, moisturisers and food residue.

How to clean nose hair trimmer

Knowing how to clean nose hair trimmer parts is especially important because nose trimmers are used in a sensitive area. Therefore, make sure to clean your nose trimmers after every use.

You should:

• Turn the trimmer off.
• Remove the trimming head if possible.
• Tap out loose hairs.
• Rinse the head if it is washable.
• Use a small brush for trapped hairs.
• Dry thoroughly before reassembling.

Do not share nose trimmers with others, and avoid using them if the skin inside your nose feels sore or irritated.

What to avoid when cleaning clippers

Avoid these common mistakes:

• Submerging a non-waterproof clipper: Always check the manufacturer’s guide to confirm whether your device is waterproof, as water can damage internal components and affect performance.
• Rinsing the charging port or motor area: These parts are not designed to get wet, and exposing them to water can cause electrical faults or permanent damage.
• Using harsh chemicals on blades or plastic parts: Strong chemicals can corrode metal blades and degrade plastics, shortening the lifespan of your clipper.
• Assembling clipper parts while wet: Moisture left on blades or attachments can lead to rust, bacteria build-up, and reduced cutting performance.
• Sharing dirty tools between users: This can spread bacteria and increase the risk of skin irritation or infection, so clippers should always be cleaned between uses.

Good clipper and trimmer maintenance is simple: after every use, remove hair, clean individual parts, disinfect the blade and keep everything dry.
