Potassium Metabisulfite - SO2 (4 oz)

Great for sterilizing my equipment and does an excellent job for what it was meant to do

Really works!! I try so many things to keep my clothes white and this definitely works butttttt after I used them and stein them again just turned brown

Use only as directed.

I use it for sanitizing in homebrewing wine. Works and is affordable.

Worked very well for what i used it for sterilization
