After every shave, store your disposable razor in a glass filled with just enough rubbing alcohol so the blades are submerged. It’s an old trick, but it works. The liquid decreases oxidation which otherwise corrodes the blade. No rubbing alcohol? Baby oil or mineral oil works just as well.
I only shave every other day, but I’ve been using the same cartridge (see photo above) for 10 months–I’m going for a year!
