When I notice my dispos are getting a bit ratty on my skin, I soak it in warm soapy water, then with a soft toothbrush I gently motion back and forth about 10 times with almost no pressure, then rinse under hot water and then "strop" the cartridge backwards on my forearm about 10 times. I haven't bought a new set of cartridges (I bought a set of 5 in 4 boxes, 20 cartridges in all) since 2015.
