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 are of monumental importance.  Thereby avoiding the risk of inaccurate assays, infections, cross contamination, etc.

It is equally important to note that it does not mean that a rinse with water is unnecessary. For example, a non-free rinsing cleaner might contain fragrances that were designed to deposit and leave a fresh scent, or it might contain corrosion inhibitors that are designed to deposit and leave behind an anti-corrosion film.

Alconox Inc. cleaners are free rinsing detergents and do not leave deposits on substrates after rinsing. There are no added dyes, fragrances, softeners or brighteners.  Additionally, the detergents are biodegradable and interfering residue free.  This ensures and allows for a surface to be cleaned, thoroughly and completely, for subsequent steps including disinfection or sterilization.  As indicated by the CDC. More specifically, residues left behind by a non free-rinsing cleaner can interfere with disinfection, such as an emollient forming a shield.
