I didn't know where to post this. I have about 4 old bottles of muriatic acid. How do I dispose of them?
I thought it went bad. These bottles look OLD! I'll just use them then. Thanks for your reply.Muriatic doesn't go bad. Why do you want to get rid of it?
Welcome to the forum.Hi, how do I dispose of an EMPTY muriatic acid container? Trash or hazardous waste?
I do the same and I am not in CA anymore. Not tainted anymore from my perspective.I recycle well-rinsed jugs of MA & LC with my other plastics. Does anyone think they are too tainted by their former contents to do this?
I have a small pool, so I only need 1 gallon of MA on hand at any time. It lives inside a home depot bucket with the lid on, behind the shed. I grab the bucket, and take it over to the pool. Pop the lid off the home depot bucket, grab the jug of MA, and pour it right next to the pool. Back into the home depot bucket it goes, lid goes on, and back behind the shed. Minimal handling, no moving with an open container. Only "risk" would be the potential build up of fumes inside the home depot bucket. I may drill a couple tiny holes to let it vent.@Sallie, be sure to store containers of MA (new or old) well away from anything metal. They can vent acid fumes that will attack and corrode metal, even if the jugs have never been opened. Don't keep them in your garage or in a shed. I store mine in an all plastic yard box, outside, in a well ventilated area of my yard, with nothing in the box that isn't plastic. Suncast makes great yard boxes for this. Some come with metal hinges, but some models don't have any metal, like this one.

I transport my acid jugs inside an all-plastic bucket. I never open the jugs outside of the bucket, and I place the bucket hanging over the edge of the pool before lifting the jug out, only over the water. After dispensing acid, the jug goes right back into the bucket. The jug, open or closed, is never over anything but the bucket or the pool water. I learned this trick from a seasoned pro that regularly handles dangerous chemicals.
I used to carelessly handle and carry acid jugs and measuring cups over my concrete deck, many years ago. The stains from an accidental slosh are still there to this day.
Does your pH not rise much?I rarely use MA - infact I am finally almost done with the last bottle from a 2pack I bought well over 5 years ago. It’s container’s integrity makes me nervous so I’m deploying a bucket method as we speak!
My pH has been 7.4 all year.Does your pH not rise much?
Not really- my ta is 60 & i have a viny pool.Does your pH not rise much?
Do that. That'll keep fumes from building up and slapping you in the face when you open the bucket, and maybe keep the inside at ambient air temp, instead of heating up.I may drill a couple tiny holes to let it vent.
16 ounces of 31.45% MA in your 32000 gallon pool would change pH by 0.1 points.I may use a cup or two a year at most.
