Q: We already recommend Tergazyme for many of our customers (brewery). But do you have any recommendations for SCUBA equipment after use? Lots of salt water exposure. Is there anything you would recommend to soak dive equipment in?
A: If Tergazyme detergent is in play already via ease of selling/recommending to them, or if your customers have it, by all means that would be a fine choice to clean SCUBA and Buoyancy Compensator Devices, for both fresh and sea water.
Q: What is the difference between Liquinox vs. Citranox? We are using Liquinox for many of our applications but are having trouble with stainless steel cleaning cannulas with a small ID. Is Citranox the answer if the residue is inorganic?
A: Although Liquinox detergent is excellent at cleaning a host of residues, Citranox cleaner is indeed the better choice if we are fairly certain this is a largely inorganic residue.
Q. is there any industry guidance on triple rinsing…any literature that you know of that this is the accepted standard for manual cleaning that you could provide me?
A. To our knowledge, there are no authoritative source documents to define how many times you should rinse glassware. The logic behind a triple rinse is that, in filling and emptying a vessel three times with water, each time you are diluting by 2 orders of magnitude. In theory . . .
