Q: Looking for a product that can lift oxidized silver along with other metals off of our glass and plastics. We are using an automated washer that takes a liquid concentrate. We need to move away from HCl, and dish soap and bleach don’t work. Manual cleaning can be considered but not preferred for the silver oxide.
A: Acidic detergents should work quite well for removing silver oxide as well as other inorganic acid labile residues.
We have a foaming and low foaming version, Citranox® Liquid Acid Cleaner and Detergent and Citrajet® Low-Foam Liquid Acid Cleaner/Rinse, for manual and automated washers, respectively. We would recommend warm 2% solutions in either case.
For washers that take a powdered detergent, we would use Alcojet® Low Foaming Powdered Detergent to remove these adherent silver oxide and other metallic residues with its chelation cleaning mechanisms.
