How are you getting on with this @arealhuman? I bought it too along with the Lintbells tooth polish, I was just wondering @JudyN how long do you do this for? Plus how often do you have to replace the microfiber cloth? I've chucked the packaging away, I've read on Amazon 4-6 weeks on the listing but someone in the questions said every 3 months. Plus how much do you rinse and reapply the polish while using? Or do you use it with toothpaste not the polish?
