How to Close Your Pool for Winter

Start with clean, balanced water: Before using your winter closing kit, thoroughly clean your pool and make sure the water is properly balanced and free of algae, dirt, and leaves.

Follow the instructions for your kit: Add the winterizing products according to the included instructions for your specific kit and pool size. Proper circulation and product distribution are important parts of the winterization process.

Finish winterizing your pool: Once the chemicals have been added and circulated as directed, lower the water level as appropriate, drain pool equipment and plumbing according to the manufacturer's instructions, and install your winter pool cover.

For complete step-by-step instructions, follow the Doheny's Winter Closing Kit Instructions.


Get Ready for Spring

When it's time to open your pool, remove water and debris from the winter cover before removing the cover. Reconnect your plumbing, raise the water level, and follow the manufacturer's instructions for restarting your pool equipment. Once your pool is ready for opening, use a pool start-up kit to help get your water clean, clear, and ready for swimming.

Shop Doheny's Pool Master Start-Up Kit for an easy way to get your pool ready for the new swimming season.

Winter Closing Instructions



Before You Begin: Make sure your pool water is properly balanced and the pool is clear of algae, dirt, leaves, and other debris before winterizing.

Kit Contents: 3.6 lb. Winter Oxidizing Tablets, three 1 lb. bags of Doheny's Chlorine Free Oxidizing Shock, 1 qt. Doheny's Metal Out, and 1 qt. Doheny's Winter Guard 35.

  1. Stop Chlorination: Stop chlorination 24 hours prior to winterization.
  2. Add Winter Guard 35: Pour the entire 1 qt. bottle of Doheny's Winter Guard 35 evenly around the entire pool.
  3. Add Metal Out: Pour the entire 1 qt. bottle of Doheny's Metal Out evenly around the pool.
  4. Add Oxidizing Shock: Wait 15 minutes, then slowly broadcast all three 1 lb. packages of Doheny's Chlorine Free Oxidizing Shock around the perimeter of the pool.
  5. Circulate: If possible, allow the pump to circulate for at least one hour to ensure all chemicals disperse evenly.
  6. Lower Water and Drain Equipment: Lower the water level and drain the lines, pump, filter, and heater of excess water according to the manufacturer's instructions. If using pool antifreeze, add it to the plumbing at this time.
  7. Prepare the Floating Dispenser: Using a screwdriver, punch holes in all dimples located on both sides of the floating dispenser. Slide the foam collar onto the dispenser. Place the floating dispenser in the pool with the smallest diameter down. Do not throw the dispenser into the pool.
  8. Cover the Pool: Cover the pool with a winter cover. Doheny's offers both solid and mesh winter covers.

Frequently Asked Questions

What comes in a Doheny’s Pool Closing Kit?

Each kit includes a winterizing chemical blend (shock, winter oxidizing tablets, and metal out), a pool closing guide, and a floating dispenser. The exact contents vary slightly by kit size.

How do I choose the right Doheny’s Pool Closing Kit for my pool?

Select a kit based on your pool’s gallon capacity. If you’re unsure of your pool size, use our online pool volume calculator to find the right fit. It’s always best to buy more if you are in between sizes.

Do I need to add anything else to my pool when using a closing kit?

In most cases, our closing kits contain everything needed. However, if you have high metal levels or a history of algae problems, you may need additional stain preventers or algaecide for extra protection. Water should be as clean and balanced as possible before adding a winter kit.

Can I use a Doheny’s Pool Closing Kit for saltwater pools?

Yes, our closing kits are safe for both chlorine and saltwater pools. Just ensure your salt cell is cleaned and turned off before closing the pool.

When is the best time to close my pool with a Doheny’s kit?

Close your pool when water temperatures consistently fall below 65°F. This prevents algae growth and ensures chemicals remain effective through winter.
