Cleaning Glassware with Acid Rinse

Q. I use a Miele glass wash machine and currently use Alcojet. I am wondering if I need to use a two step wash with an acid rinse to be sure the glass is residue free. What detergents would you recommend for either a one or two step cleaning process?

A. Alcojet® Low Foaming Powdered Detergent detergent is free-rinsing, meaning it rinses completely away with water and without rinse aids. There are no softeners, brighteners, fragrances or other residues that are not involved with the specific action of aqueous cleaning. Having said that, we know of many applications that do still involve an acid rinse/wash. Acidic cleaners like Citrajet® Low-Foam Liquid Acid Cleaner/Rinse detergent are better at removing inorganic residues, oxides and other acid labile substances.

So, in short Alcojet powder can be used by itself, but depending on your day to day residues, a two step wash could be warranted. Also note that Citrajet cleaner is only available in a liquid concentrate and you would need a liquid dispensing system on your washer.  Alternatively, you could potentially add Citrajet liquid concentrate to the bottom of the washer at the end of the wash cycle.

Download the Alconox Guide to Critical Cleaning for more helpful advice on detergent selection. Also consult the Alcojet and Citrajet SDS and technical bulletins for additional information. Samples are also available here after answering a brief questionnaire.
