As temperatures drop and winter approaches, it’s time to prepare your pool for the off-season. Proper storage of chemicals, equipment, and accessories protects your investment, prevents damage, and ensures a smooth reopening next spring! Here’s how to store your pool supplies efficiently.
Plan Ahead: Inventory & Preparation
Take stock of your supplies
Make a list of chemicals, test kits, pumps, hoses, covers, cleaning tools, and filter parts. Knowing what you have prevents duplicates and ensures proper storage.
Clean and dry everything
Rinse hoses, brushes, nets, and other accessories to remove dirt and chemical residue. Dry completely in sunlight or a ventilated area to prevent corrosion, mold, or chemical reactions.
Choose the right storage area
Select a cool, dry space with stable temperatures, such as a basement, garage, or shed. Avoid unheated areas where chemicals could freeze, and keep equipment off damp floors.
Storing Chemicals Safely
- Keep containers sealed and labeled
Never transfer chemicals to unmarked containers! Secure lids tightly. - Store by type
Keep oxidizers like chlorine and shock separate from acids, algaecides, and metal treatments to prevent accidental reactions. - Elevate off the floor
Use shelves or pallets to avoid spills and flooding damage. - Avoid extreme temperatures
Freezing weather can degrade chemicals, while heat can accelerate breakdown. Temperature-controlled garages or basements are ideal. - Ventilation matters
A well-ventilated cabinet or closet disperses fumes and reduces risks.
Pro Tip: Extra chlorine or shock, like Super Zappit Shock, should be sealed and stored in a cool, dry place to retain potency for next season.
Equipment & Machinery Storage
- Disconnect and drain
Remove hoses, plumbing, and attachments. Drain pumps, filters, heaters, and other equipment to prevent freeze damage. - Lubricate seals and O-rings
Apply silicone lubricant to threads, gaskets, and rubber parts to prevent cracking. - Wrap cords and cables
Coil loosely, label, and protect from dust or rodents. - Cover large equipment
Use breathable covers or cloth tarps to shield from dust without trapping moisture.
Pro Tip: Coil hoses loosely and hang when possible. Quality hoses, like the PoolStyle Pro-Flex Vacuum Hose, last longer with proper storage.
Accessories, Tools & Small Items
- Covers & safety nets
Clean, dry, fold or roll loosely, and store in breathable bags or on racks to avoid mildew. - Test kits and reagents
Keep in original sealed packaging in a dark, dry drawer or cabinet away from chemicals. - Hoses, poles, brushes, nets
Coil hoses gently and hang tools on wall racks to maintain shape and free floor space. - Spare parts & fittings
Use labeled bins or clear boxes for easy organization. - Seasonal Kits
If you use a pool closing or opening kit, store it in a dry, temperature-controlled area to keep all chemicals effective. Kits like the Safe-T-Zone Closing Kit simplify seasonal transitions.
Mid-Winter Check
Don’t “set and forget.” Inspect chemical containers for leaks, look for moisture, ensure equipment covers are intact, and check that storage temperatures remain stable. Address issues promptly to protect your supplies.
Reopening Season
When reopening your pool, follow these steps:
- Check if your chemicals are still within their shelf life
- Reassemble equipment and inspect for damage
- Replace degraded items
- Recalibrate test kits and automation gear
