Q. Please provide advice on cleaning iron residues, Fe+2 and Fe+3, in lab glassware. We need to clean down to sub ppm levels.
A. The best iron salt removing detergent for manual cleaning of lab glassware is Citranox® Liquid Acid Cleaner and Detergent. Citranox detergent is a mild acid, high chelating detergent for high performance removal of metal oxides, scale, salts and inorganic residues in manual and ultrasonic cleaning. It is also corrosion inhibited and free rinsing for reliable results and no interfering residues.
For your glassware, use a warm 2% solution (20 mL/L) to soak and scrub with and then rinse thoroughly in deioinized water.
If you are looking to utilize a washer for this application, Citrajet® Low-Foam Liquid Acid Cleaner/Rinse is your low foaming option.
