Our razor cleaner is carefully formulated with glycerin and cocamidoamide DEA. Designed specifically for effectively removing oil stains and stubble residues from razor heads and filters. The usage method is extremely convenient: Turn off the device make sure the razor is powered off and keep it dry before use. Spray the cleaner evenly on the blade and the filter area to cover the stains and residues. Let it stand for three minutes so that the cleaning ingredients can fully break down grease and impurities. Gently scrub the blade head and crevices with a brush to remove stubborn residues. Rinse with clean water dry and let it air dry naturally before continuing to use. And it can help lubricate the blade to improve shaving smoothness and reduce friction discomfort.
