While using a disposable razor multiple times saves money, germs and bacteria grow on the blades after each use. Lotion and skin particles can also get caught between the blades. Sterilizing your razor before shaving kills off the germs and makes the blade as safe as new. Soaking the blade in chemical cleaning agents will kill the majority of bacteria, as will setting the razor in boiling water. A clean razor can be used as long as the blades stay sharp.

Things You'll Need

  • Dish soap
  • Toothbrush
  • Rubbing alcohol or hydrogen peroxide
  • Bowl
  • Saucepan
  • Kitchen spoon

Soaking

Step 1

Rinse off the blades with hot water.

Step 2

Add a dab of dish soap to the blades, and scrub the razor with a toothbrush to remove any grime. The thin toothbrush bristles can reach in between the razor blades, allowing you to remove buildup such as dried shaving cream.

Step 3

Wash the soap off the razor using hot water again, then apply a cleaning agent like rubbing alcohol or hydrogen peroxide. Pour the cleaning agent into a small bowl, and soak the razor, using just enough of the cleaning agent to completely cover it. Soak it for 10 minutes if using rubbing alcohol or 30 minutes if using hydrogen peroxide.

Step 4

Remove the razor from the bowl, and rinse it off with hot water before using it to shave.

Boiling

Step 1

Put a saucepan on the stove, and fill it with enough water to boil for 10 minutes.

Step 2

Put the razor in the pan, and close the top of the lid.

Step 3

Turn the stove to “High,” and wait for the water to start boiling. Allow the water to boil for 10 minutes.

Step 4

Remove the pan from the hot stove, and take off the lid. Let the water cool for 10 minutes, then scoop the razor out with a kitchen spoon.

Tip

  • The razor can also be soaked in white vinegar for an hour to kill bacteria. This is a natural alternative, but the vinegar won't sterilize the blade as much as rubbing alcohol or hydrogen peroxide.
