Q. What is the maximum wash temperature for Liquinox? At this maximum temperature is there an accelerated breakdown of detergent?
A. Liquinox is heat stable all the way to boiling at standard temperature and pressure conditions. From a practical standpoint, there are some detergency mechanisms that begin to break down mechanistically as you approach boiling. Emulsions begin to become less stable as you approach within a couple degrees of boiling. If emulsifying is not a critical cleaning mechanism, this may not be relevant to you.

Q. Can you lower the pH of Tergazyme using Citric acid or vinegar?
A. Yes. To adjust the pH of a 1% Tergazyme solution from pH 9.5 to about pH 8.5 add 0.1 grams of 99% anhydrous citric acid for each 5 grams of Tergazyme.

Q. What medical device information is in the Medical Device Cleaning Validation References?
A. The Medical Device Cleaning Validation References for Alconox Detergents contains information about identifying residues, selecting a residue detection method, selecting a sampling method, setting residue acceptance criteria, and more.

Q. We are looking to use Liquinox in an automated cleaning machine. The cleaner would be agitated ultrasonically and pumped to/from the storage tank by magnetic drive pumps. We are worried that the Liquinox will foam during the transfer by pump. Is this a valid concern? If so, is there an alternative cleaner that we could use in place of the Liquinox?

Q. Have you evaluated effects of Alconox on metals, elastomers, thermoplastics, and rubbers? Do you have a chemical resistance table/chart for Alconox? Thanks.
A. Alconox is compatible with a wide range of metals and plastics. You can contact cleaning@alconox.com to receive a copy of the current chemical compatibility spreadsheet. In general Alconox can be used to clean stainless steel, polyethylene, polypropylene, synthetic rubber, and PEEK.
