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 . . .
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
Q. What can we do to reduce cleaning time? We want to be as optimal and thorough in our cleaning as possible.
A. At Alconox Inc we recognize that manual cleaning may take minutes, spray cleaning seconds, and soaking may take hours, possibly overnight, to achieve comparable cleanliness. Read more….
We are using a bath of Alconox powder for cleaning several metallic parts. We have found that both the concentration of Alconox, along with a set duration brings about the correct end result. As the wash solution is created at the beginning of each working shift, a gradual ‘weakening’ of the process occurs. In some instances, we resort to manually replenishing the tank with a fresh mix mid-shift. Would you have any general advice?
