Replacing HCl to remove MnO2
Q. Currently using Hydrochloric Acid (HCL) to remove residual Manganese Oxide (MnO2)from glassware. Following ASTM D1721 instructions. Do you offer a cleaner that could do the same job and assist in replacing HCL and remove the MnO2?
A. Yes. Use a 2% Citranox (2.5 oz/gal or 20 mL/L) solution followed by a thorough rinse to remove Manganese Oxide from glassware. The mild organic acid chelating agents will remove MnO2 more safely than hydrochloric acid.
