Sodium Metasilicate

Na2SiO3
nasty stuff to handle. I ordered some for testing and poured it into buckets. Every time someone opens a bucket everyone around starts coughing. A respirator is recommended if you are going to handle it – not a dust mask. It will etch glass. It cleans very well! Strips labels and completely dissolves the adhesives. It’s what makes PBW work so much better than Oxiclean, One Step, etc… . Some powders list Sodium Silicate as an ingredient. From what I have seen, Sodium Silicate is always a liquid. The name Sodium Silicate is a synonym, which is also used for Sodium Metasilicate, and a couple other variations. Liquid Sodium Silicate has another use in brewing, it is the Kieselsol in K.C.
