Pulsetto needs a drop of gel so the current can reach your vagus nerve and help you relax. The problem is that leftover gel dries into hard flakes that make the device look dirty. Cheap wipes are mostly water and can slowly rust the metal parts. Pulsetto Wipes remove gel in one swipe while killing 99.97% of bacteria with a safe, non-corrosive formula — so your Pulsetto stays fresh, hygienic, and working like new.
