Liquinox vs. Citranox
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.
Guidelines for Triple Rinsing
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 . . .
Cleaning Fungus Residues from Mycoinsecticide
Q: How do you clean biofilm residuals and the fungus residue from mycoinsecticide? A: A mycoinsecticide is a microbial insecticide whose active ingredient is a living fungus that is pathogenic to a targeted group of pests, insects and other biocontrolled species. It is used in industries from food production, biotech, cannabis and of course the laboratories supporting those industries.
Extra Foam Please?
Q: Since foaming is so critical to COP methods, should operators be agitating the solution(s) to produce foam before and during manual cleanings?
A: Mechanical energy, agitation, and plain old elbow grease, are vital weapons in cleaning and Clean-Out-Of-Place applications. So we would recommend that wherever possible, mechanical energy be applied to remove unwanted residues from the surface we are trying to clean. This will
Replacing Isopropyl Alcohol in Cleaning
Q. I’ve been told that we should no longer use isopropyl alcohol for cleaning our pharmaceutical equipment. What should we use instead?
A. In pharmaceutical cleaning applications, isopropyl alcohol (IPA) is less than ideal. Alcohol will clean residues which are soluble in alcohol, but that is a limited range. Using critical cleaning, aqueous detergents are a far more robust and will allow for more effective cleaning processes.
