Do Enzymatic Detergents Disinfect?
Q. We have been using Tergazyme to clean lenses and cuvettes for our light scattering equipment and it works flawlessly! My question is: Does Tergazyme enzyme detergent have any disinfection properties, like killing of bacteria such as E. coli, or viruses?
Dilution Precision in Concentration Measurements
Q. Do I determine detergent dilution by weight or by volume or both?
A. In a laboratory setting, the most common method is to either make a weight/weight dilution (10-20 g Alconox detergent in 990 g of water), or a weight/volume dilution (10-20 g Alconox in 990 mL of water) for 1-2% solutions. In manufacturing situations, often directions are written volume/volume or volume/weight.
Removing Polyurethane Glue From Stainless Steel Bolts
Q: We are having trouble removing polyurethane glue from stainless steel bolts.
A: Adherent residues can be tough. And clearly glue is adherent, per design.
For this application we want to increase temperature to expedite the cleaning effort as much as possible, and soften the glue. We also want to up the concentration to ensure having sufficient detergent capacity.
Cosmetics Cleaning: Removing Deodorant From Stainless Tanks
Q: How can we clean residual deodorant from our stainless steel tanks? It is proving very difficult. It is largely AlCl3.
A: Deodorant, designed to stay in place for obvious reasons, can be quite adherent on processing equipment. If it stays on skin for extended periods, which is designed to avoid residues, imagine what it does to stainless steel!
Cleaning Brass Gun Cartridges
Q. I am concerned about the acidic reaction the vinegar may have with brass gun cartridges. Do you have a product that will clean brass ultrasonically and not have the issues of using vinegar and if so could you send some samples?
