The bottle is the container, not a suggestion
Pool chemicals are often oxidizers, acids, or biocides, and they do not become harmless because the pool is gone. Leave them in the original labeled containers with the cap tight. Do not pour chlorine tablets down the sink, do not pour liquid shock on the driveway, do not mix products to see if they fizz, and do not evaporate a tray of acid in the sun. Do not burn empty-looking jugs in a fire. Do not dump a half bucket into a storm drain because rain will dilute it. If two products were already mixed by mistake and the bucket is warm or fuming, get people away and call your local emergency number for instructions. This article is about intact leftovers, not about experimenting with them. Keep children and pets out of the cabinet while you sort.
Household hazardous waste is the destination
Call the household hazardous waste program and ask whether residential pool chemicals are accepted, which products they refuse, and whether the container must still have its label. Say pool chlorine, algaecide, or muriatic acid by name. A construction debris site and a yard-waste pile are the wrong places. A retail take-back, if one exists near you, must be confirmed by a phone call, not by an old sticker. If you search Dumpmapper by ZIP code or city, treat the listing as a lead only. Hours and accepted products can be out of date. Do not combine a carload of chemicals into one drum to save space. Mixing is how people get a reaction in the trunk. Boxed, upright, and capped is the ride.
Empty jugs are not automatically recycling
A jug that still holds chemical is hazardous waste even if it feels light. Take it to the program. A jug the program has told you is empty enough to recycle or trash can then follow that instruction, and not before. Do not rinse a chlorine jug into the street so the plastic looks clean. At the drop-off, leave products in the car until staff tell you to unload. They often want oxidizers kept away from acids. Follow their sorting. If they refuse a leaking container, ask how to repack it and do not set it on the curb on the way home. The pool cover, the pump, and the chemicals are different loads. Do not hide a jug of shock in the folded cover.

Questions people ask
Can I dry chlorine tablets and throw them in the trash?
No. Do not dry, dissolve, or trash them. Take tablets to the household hazardous waste program in the original container.
What if the label has fallen off?
Tell the program you do not know the product and keep that container away from the ones you can identify. Do not guess and pour them together.
