Corncob cleaning media GM 20

GM 20 corncob cleaning media is the ultimate solution for deep and effective cleaning of brass cases. It is designed to remove contaminants that can affect the reliability and accuracy of your cases.

GM 20 corncob cleaning media is grained in 0.56-1.00mm, making it the ideal choice for cleaning a variety of ammo calibers. Its fine texture allows you to deeply clean the inside of cases and remove residue from their walls.

The cleaning process is simple: simply place the used brass cases in a container of GM 20 corncob cleaning media and gently mix them as required. Unlike walnut grit, corncob media dusts less and leaves the surface shiny. We also recommend adding Sitol, which is designed for cleaning and polishing precious metal items. Sitol is dispensed directly into the abrasive.
If you want to keep your cartridges clean and polished, wash the cartridges in walnut cleaning media in the first step, which will handle coarse dirt, and wash the cartridges in corncob cleaning media in the second step, which will finish the cartridges and polish them nicely.
