Can razor blades be wiped with alcohol?

sure. The razor blade can be wiped and disinfected with alcohol (recommended 75% medical concentration), which can effectively kill bacteria and evaporate quickly, without leaving any residual moisture. Attention should be paid when wiping:

Gentle operation: avoid damaging the sharpness of the blade with excessive friction;

Thoroughly dry: prevent slight oxidation of metals due to incomplete evaporation of alcohol;

Be cautious with coated blades: If the blades contain special anti rust/lubricating coatings, alcohol may affect their effectiveness. It is recommended to refer to the product instructions.

Regular disinfection can extend the hygiene of the blade, but it cannot replace regular replacement. Even after passivation, it still needs to be replaced in a timely manner.
