Cheapest source for muriatic acid?

[fcfrey]

[QUOTE=dafletcha;37282]I felt like I hit the jackpot a few weeks ago when I wandered into FoodMaxx and found Muriatic Acid selling for around $2.50/gal. I should have bought their whole stock then and there. But how was I to know that they would soon stop carrying it? QUOTE]

Next time you find a bargain like that should you take advantage of it (a s s uming you can safely store it)?? My question is -- will it degrade in time -- I don't seem to use much acid at all.

Muriatic Acid (31.45% hydrochloric acid) has a multi-year shelf life so you should be fine. It also has a much lower freezing point than pure water (-50.8F or -46C) so unless you live in the Artic, you can leave it outside.
