In order to clean the bronze screens or dies you have to wash them with water only (the use of chemical agents and putting them into the dishwasher could lead to oxidation). After that you may remove the residues on the inside of the screen (to make this step easier we created those cleaning tools), and finally you just dry it by hand. To clean the PVD dies, simply insert them into the dishwasher, remove the inner residues after washing them and let them dry.
