Pool chemicals need dry, cool, and separated storage.

Keep them dry, cool, and separated.

Pool chemicals don’t need fancy cabinets, but they do need basic common sense. Store them in a dry, well-ventilated area out of direct sunlight. A garage shelf works, but not next to the water heater or lawn mower gas.

The bigger deal is keeping different chemicals apart. Chlorine and acid should never touch each other — they react violently. Same goes for storing pool chemicals near fertilizers, paints, or solvents. A small plastic tub for each type is cheap insurance.

Moisture is the enemy. Even humidity can cause some chemicals to clump or degrade. If the lid isn’t sealed tight, you’re asking for trouble. And never store them on the ground — flooding happens.

One more thing: don’t buy in bulk unless you actually go through it fast. Half a bucket of five-year-old shock is a guessing game, not a pool chemical.

Future You will appreciate not having a chemical fire.
