Q: What can we do to replace n-propyl bromide? We are cleaning grease and oil from stainless steel. We had heard Citranox might do the job well. A: The compound n-propyl bromide is often used in vapor degreasing and is considered to be associated with some serious health risks and is hazardous. We would certainly recommend you switch to a drain-safe, biodegradable, … [Read more...] about Non Hazardous Replacement for N-Propyl Bromide

Defining Free Rinsing Detergent
Q. Your website and literature often describes your detergents as free rinsing. What does free rinsing detergent mean? A. A free rinsing detergent means it will rinse away very easily or freely. This is vital to critical cleaning applications. Analytical glassware, medical device implants or biopharm process lines are just a few examples where clean, residue-free surfaces … [Read more...] about Defining Free Rinsing Detergent
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 … [Read more...] about Dilution Precision in Concentration Measurements
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. We … [Read more...] about Removing Polyurethane Glue From Stainless Steel Bolts
Ultrasonic Cleaner for Parts and Towels
Q. I'm looking for a cleaning solution to use in our industrial ultrasonic cleaner that is similar to the old style competitor detergent. We use it occasionally for general cleaning, removal of machining oils, cleaning for high vacuum use, and to lightly etch the oxides off of copper. Would you recommend Alconox or Liquinox detergent? How long would a pre-mix of the … [Read more...] about Ultrasonic Cleaner for Parts and Towels
