So congratulations, you've joined the ongoing movement toward switching to a bamboo metal Safety Razor. This will mean, you will need to give (your precious gem) a little more love and attention if you want the longest possible lifespan. #oneecostep.
Give your razor a rinse after every use, you'll want the pressure of tap (shower isn't usually strong enough) against the back of the razor head to dislodge any hair and oil/soap build-up. Then wipe dry, and store in a cool, dry place or your Eco-Audrey Bag!
Each time you disassemble the razor to change your blade, use this an opportunity to give it a proper wash.Do not use rubbing alcoholor harsh disinfectants as this can strip the protective anti-rust layer on the razor, soap and water will suffice.
Personally, I use a cloth and wipe clean the blade.
