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.

Q: Many of your Tergazyme related TechNotes and recommendations include warm temperatures. Warm temperatures can still denature some hormones and proteins thus causing cleaning problems. I would probably start with a cool (room temp or cooler) rinse (water). Then move to the 1-2% cleaning solution in warmer temperatures. Agreed?

Q: What can we do to replace n-propyl bromide? We are cleaning grease and oil from stainless steel. We had heard Citranox might do the job well.
A: The compound n-propyl bromide is often used in vapor degreasing and is considered to be associated with some serious health risks and is hazardous. We would certainly recommend you switch to a drain-safe, biodegradable, aqueous detergents.
