You can purchase Gerber cleaning pads from any Gerber supplier. If you order any Duracoat cartridges, they come with a cleaning pad. Also, you can use a lint free pad with 99% Isopropyl Alcohol, that you possibly can get at a pharmaceutical supplier or electronic supplier, though I never seem to be able to find it. Better double check the Gerber website for the fast facts on cleaning to get the official recomendation.
