Most pool owners have some sort of pool chemical on hand at all times throughout the season. Whether you didn't use the entire 6-count of pool shock, or you're simply stocking up on chlorinating tablets at the beginning of the season to avoid last-minute store trips, there’s a good chance you'll have to find a safe spot to put your pool products. And of course, you may need to find a longer-term storage solution for any leftover chemicals during the off-season too.

Where should I store my pool chemicals?

In order to prevent any unnecessary exposure to toxins, pool chemicals should be stored in an area that provides good ventilation to remove any toxic vapors, fumes, mists, or airborne dust. Look for a cool, dry, secure, and well-ventilated area. When you're choosing a storage spot, keep in mind that many chemicals, especially oxidizers and strong acids, can corrode some metals, causing rust or other damage. Finally, never store oxidizers and organic chemicals like gasoline in areas that are poorly ventilated or frequently used by people.

How long will my pool chemicals be effective?

Effectiveness depends on the specific pool chemical as well as the storage conditions. Most all pool chemicals should be used within two pool seasons; however, you should use chlorine and bromine oxidizers and sanitizers within the season you buy them, especially liquid chlorine or calcium hypochlorite.

What’s the biggest mistake?

Not keeping pool chemicals in a cool and dry spot is not only a common mistake, but also a mistake that can be costly. Allowing oxidizers to get wet can be dangerous. And allowing liquids to freeze can make the product unusable.

My pool chemicals expired – can I still use them?

Unless a product has separated, become badly discolored, or developed a foul odor, it will likely still work, just not as effectively as when it’s fresh.

So, can I leave my pool chemicals outside?

Many pool chemicals react poorly to extreme temperatures – cold or hot, which is obviously what you risk when you store them outside. If you store your pool chemicals in an area that gets warmer than 95 degrees Fahrenheit, the expansion of liquids or the release of gases caused by high temperatures can cause containers to leak or spill. In some cases, chemicals that heat up can cause dangerous conditions that could lead to fire or an explosion. On the other hand, if liquid chemicals are allowed to freeze, they could begin to separate and lose effectiveness or become unusable.
