How to Actually Clean Your Razor (Most People Skip the Step That Matters)

Decent razor. Good shaving cream. Rinse the blade when you are done. And your skin still breaks out, burns, or stays rough after every shave. The problem is not your technique. It is that rinsing a razor is not the same as cleaning it. There is a difference, and it shows up on your skin.

What rinsing actually does (and what it does not)

When people ask how to clean a razor, they usually mean running it under the tap. That removes loose hair and shaving cream. It does nothing about the harmful bacteria and dead skin cells that often get trapped between the blades.

Those are the things that go back onto your skin at the next shave. That is the clean razor, better skin connection that most people never make: a cleaner blade means less bacterial transfer, which means less irritation, fewer spots, and better skin.

A 2026 study in Frontiers in Microbiology found that shavers carry multidrug-resistant bacteria between uses, and that disinfecting the blade head measurably reduced that bacterial load. The difference was not technique. It was whether the blade was disinfected or only rinsed.

How to clean your razor properly

The full process takes under a minute. Here is exactly what it looks like.

Step 1: Rinse straight after shaving

Hold the razor under warm running water immediately after you finish. Angle the head so water flows between the blades. This clears the visible debris. Left between your blades. 

Step 2: Apply a disinfectant spray

This is the step most people skip. Knowing how to clean a razor after shaving properly means using something that actually kills bacteria. Spray a razor disinfectant spray directly onto the blade head and allow a few seconds for it to work.

The CS500 from London Skin Labs is built specially for this step. The medical-grade formula reaches between the blades and eliminates bacteria. The high blast spray and precise nozzle flushes dirt, trapped hair and harmful bacteria in one blast. 

Step 3: Clear between the blades

How to clean a razor head properly means getting into the spaces between the blades. That is where the residue that causes ongoing skin irritation lives. If your product has a cleaning attachment, use it here.

Step 4: Dry it properly and store it dry

Shake off excess moisture. Leave the razor upright somewhere dry, not on the shower edge and not flat on a wet surface. A damp razor in a humid bathroom is a bacterial breeding ground. 

How to clean an electric shaver head

How to clean electric shaver heads follows the same logic but with a slightly different process.

For waterproof models: open the head, tap out loose hair and dirt over a bin, rinse under warm water, clear the foil and cutter block with the included brush, then apply a shaver disinfectant spray. Let it dry fully before reassembling.

For non-waterproof models: skip the rinse. Dry brush to clear debris, then apply a disinfectant spray for razors and wipe the exterior.

Frequently Asked Questions

How often should I clean my razor?

After every use. Bacteria accumulate on wet blades quickly, and rinsing alone does not remove them. Disinfecting after each shave is what breaks the contamination cycle.

Does cleaning a razor actually improve skin?

Yes. Fewer bacteria on the blade means less bacterial transfer during shaving. Most people notice fewer post-shave spots and less redness with consistent disinfection.

How do I clean an electric shaver head?

Open the head, clear debris, rinse if the device is waterproof, clean the foil and cutter block with the included brush, apply a shaver disinfectant spray, and allow it to dry completely before reassembling.

Can I use household disinfectant on my razor?

Not recommended. Household products can leave residue that irritates skin and degrades blade coatings. Use a product formulated specifically for grooming tools like CS500 Razor Disinfectant Spray.

Does cleaning the blade make it last longer?

Yes. Residue and bacteria accelerate blade corrosion. Removing them after each shave extends the useful life of the blade and keeps shaves comfortable for longer.

What is the best way to store a razor between uses?

Upright in a holder with airflow, away from direct shower spray and pooled water. A damp environment accelerates bacterial growth between shaves.
