Q. What detergents and recommended dosing should I use in my laboratory glassware washer?  Are they safe to use in a stainless steel washer and are they residue-free?

A. All of our low foaming cleaners are safe for use on stainless steel dishwashers.

For use in a typical small under counter glassware washer, Alcojet® Low Foaming Powdered Detergent and Citrajet® Low-Foam Liquid Acid Cleaner/Rinse are the best cleaners to use. If the laboratory washer has a liquid dosing system with tubes that go into the detergent bottle and pump in the correct dose of liquid detergent, then I would recommend using Solujet® Low-Foaming Phosphate-Free Liquid instead of Alcojet detergent. (Normally a small under counter washer does not have this kind of liquid dosing system; typically larger ones do.)

If for example, your wash cycle uses 3.5 L of water and the rinse cycle is 1.75 L of water,  a dosing of 35 g of Alcojet and 35 mL of Citrajet cleaners is the way to go.

Alcojet, Solujet and Citrajet detergents are all biodegradable, free-rinsing, interfering residue-free.  You can read further on the ensuring residue-free glassware in your labware washer as needed.
