Date on Muratic Acid

I know the dates on the bleach are important, but what about MA? I bought a two pack from Home Depot, and there is no date on the cardboard box. Or at least that I could see. When opening the box at home, and looking at bottle, I saw no print on it like on the bleach.

Muriatic acid is very stable and will literally last for years. It pretty much has an infinite shelf life if stored in a tightly sealed bottle.

This. In pressure washing it is one of our lesser used chemicals and age or concentration were never even a consideration. And trust me, we knew when our chems had aged/weakened because the job got harder and took longer. You could almost measure chem concentration by the employees time reports.
