Muriatic acid storage

[chem geek]

Thanks for the info. I guess I'll have to move it to another area in the garage since now it sits a few feet away from my car. Denise

The issue with storing acid near metal is if the container is not air tight since the hydrochloric acid fumes are indeed very very corrosive. It's more of a "just in case" rule just in case the cap is not securely tightened or if the container is not otherwise air-tight. I have mine stored in my pool shed (which is ventilated), but I tightened the cap quite strongly and did an extensive "sniff-test" around the cap and the bottle and also took a moistened (with distilled water) pH test strip and left it near the bottle and found no change in pH. Of course, that probably just shows what a geek I am rather than proving that much about safely storing Muriatic Acid!
