Shelf life of Diversol in solution

Jack--hours.

The pink stuff is potassium permanganate that acts as a catalyst to release chlorine. The rest of the material is a super detergent that seem to do the best job of getting scummy residues off glass. It is to be mixed with hot water, and used for up to an hour's soak, and NOT stored or re-used. When the rinsing is done the bottle is ready to fill. You should fill within 15 minutes of rinsing.

The stuff that can be stored for years is potassium (or sodium) metabisulfite, I use 1% solution. As long as it smells, it will work. But it does NOT wash, only sanitize.

There is a third product that is less effective--I have never bothered to use it as the above work so well. The Diversol is the best choice for beer (less acid, therefore MUCH more sensitive to bottle cleanness and sanitation).

Potassium Metabisulfite has a shelf life of six months when the powder is stored properly. As an aqueous solution exposed to air it is less. I typically keep a 10% solution no more than 3 months.
