Cleaning Diatomaceous Earth & MICA Residues
Q. Cleaning is difficult due to geometry of parts with hard to clean areas. Aluminum mandrels are used for dipping neoprene; mandrels are predipped in calcium carbonate/mica/diatomaceous earth and baked at 200F. Acid dissolves carbonate but doesn’t remove all DE/mica.
A. We suggest cleaning in warm 2% Citranox® (circa 120 deg F, 2.5 oz/gal or 20 mL/L) followed by a thorough rinse. Citranox® is a mild …
Addition of Acid Rinse to Wash Cycle
We have a glass wash machine and use Alcojet for it. We would like to know if you need to include a neutralizing agent like Citrajet as part of the wash cycle (acid rinse)? Alcojet® Low Foaming Powdered Detergent is what we would call free-rinsing, meaning it rinses completely away with water without rinse aids.
Similar detergent to Liqui-Jet 2?
Q: We’re looking for a detergent solution like Liqui-Jet™2 Instrument Detergent by Steris. We need it to clean the drain in our microbiology autoclave, so it should be able to target any media or agar that may be clogging the drain.…
Cleaning Space Environment Simulation Chambers
Q. We are currently using Alconox® for cleaning of space environment simulation chambers. What do you recommend for a process to clean steel piping contaminated with DC-704 and Fryquel 550 and turbomolecular vacuum pump backing piping at JSC/NAS?
A. Alconox® detergent is the right choice, but vacuum pump grease is a very heavy difficult to remove residue. We recommend using very hot (170 deg F if possible) 2% Alconox® (20 g/L) followed by a very hot first rinse…
Ambient Temperature for Cleaning
Q. I am manufacturing engineer and I have a question regarding Alconox powdered precision cleaner. Your catalog says that the minimum cleaning temperature when using Alconox should be ambient temperature. How much is Ambient Temperature exactly? Our clean rooms have a temperature of approximately 21°C, which means that after heating it for preparation it will cool down through the day. Should we keep it over 21 °C?
