How to maintain an inflatable swimming pool in winter?

As the leaves start to turn and the air gets that crisp, autumnal bite, there's one summer staple that's probably been on your mind: your inflatable swimming pool. You know, the one that turned your backyard into a mini oasis back in July—the spot where the kids splashed until sunset, where you hosted that epic pool party with the neighbors, and where you spent countless weekends floating on an inflatable water mattress sun deck, pretending you were on a tropical vacation. But now, with winter on the horizon, it's time to say goodbye—temporarily, of course. The question is: how do you make sure that beloved pool survives the cold, snow, and damp so it's ready to bounce back (literally) next summer?

Let's face it: inflatable swimming pools are amazing for their portability and fun factor, but they're not exactly built to withstand winter's wrath on their own. Leave them out in the elements, and you could be looking at cracked seams, mildew growth, or even permanent damage come spring. But don't worry—with a little care and some proactive steps, you can keep your pool in tip-top shape until the temperatures rise again. In this guide, we'll walk through everything you need to know, from cleaning and draining to storage and winter checks. Let's dive in (pun absolutely intended).

Step 1: Clean the Pool Thoroughly—No Shortcuts Here

First things first: you can't store a dirty pool. Think about it—if you leave leaves, algae, or even tiny bits of debris in there over winter, they'll break down, create moisture, and turn into a breeding ground for mold and mildew. And trust me, trying to scrub mold off a deflated pool in March is not how anyone wants to spend their weekend. So grab your pool skimmer, a soft brush, and let's get to work.

Start by removing all large debris: leaves, twigs, bugs, and any toys that might have floated to the bottom. A handheld skimmer net works great for this—just make sure to get into the corners and along the edges, where stuff likes to hide. Next, it's time to tackle the walls and floor. Use a soft-bristled brush (avoid anything abrasive, like a wire brush, which can scratch the PVC material) and gently scrub away any algae or slimy buildup. If you notice stubborn spots, mix a solution of warm water and mild dish soap (no harsh chemicals—bleach or ammonia can damage the pool's material) and use that to spot-clean. For extra credit, if your pool has a filter, take it apart and clean it too—gunk in the filter can trap moisture, which is bad news for storage.

Once you've scrubbed the inside, rinse the pool thoroughly with a hose. Make sure to get rid of all soap residue—you don't want that sitting on the material over winter. Then, use a clean towel or a wet-dry vacuum to soak up any remaining water. The goal here is to get the pool as clean and dry as possible before moving on to the next step. Pro tip: If you have a small inflatable air mattress, you can use the same gentle cleaning method—mild soap, soft brush, thorough rinsing—so this is a good time to give that a once-over too!

Step 2: Drain the Pool Completely—Even the Last ｄｒｏｐ

Now that your pool is sparkling clean, it's time to drain the water. This might seem obvious, but you'd be surprised how many people skip this step or only drain most of the water, leaving a few inches at the bottom. Big mistake. Any leftover water will freeze in winter, expand, and could stretch or crack the pool's seams. So let's do this right.

Most inflatable swimming pools have a drain plug near the bottom—simply twist that open and let the water flow out. If yours doesn't have a plug, you can siphon the water using a garden hose: submerge one end of the hose in the pool, suck on the other end until water starts flowing (gross, but effective), and then direct the hose away from the pool to drain. If you're worried about water damage to your yard, position the hose so the water drains onto a lawn or flower bed (just avoid areas with poor drainage, where it might pool and freeze). For smaller pools, you can even tip them gently to pour out the remaining water—just be careful not to strain the seams.

Once the majority of the water is out, it's time to get rid of the last little bits. Use a sponge or a towel to soak up water from the bottom and corners—don't forget the areas around the drain plug, which can trap water. If you have a wet-dry vacuum, that's even better—run it over the floor and walls to suck up any moisture you might have missed. Then, leave the pool inflated for a few hours (or even overnight, if the weather is warm and dry) to air out. This helps evaporate any remaining water that's hiding in crevices. You want the pool to be completely dry before deflating—no dampness allowed.

Step 3: Inspect for Damage—Catch Issues Before They Worsen

With the pool clean and dry, now's the perfect time to check for any damage. Small holes, tears, or weak seams might not seem like a big deal now, but winter storage can make them worse. Freezing temperatures can make the material brittle, and any existing damage could split open when you deflate or store it. So grab a flashlight (to see better) and give the pool a thorough once-over.

Start by inflating the pool slightly—just enough so the walls are firm but not fully expanded. This makes it easier to spot issues. Look for: small punctures (often from sharp objects like thorns or dog claws), tears along the seams, or areas where the material is thinning or discolored. Run your hand gently over the surface—you might feel a small hole before you see it. If you find a puncture, don't panic! Most inflatable pools come with a repair kit, which includes patches and adhesive. Clean the area around the hole with rubbing alcohol, let it dry, then apply the patch according to the kit's instructions. For larger tears or seam damage, you might need a stronger adhesive (like vinyl repair glue) or even professional help—but for small holes, a DIY patch should do the trick.

Don't forget to check the valves too! The valve caps can crack or get lost, which can let moisture in during storage. If a valve cap is missing, ｒｅｐｌａｃｅ it with a new one (you can find these online or at pool supply stores). Also, make sure the valves themselves are working properly—they should close tightly to prevent air (and water) from getting in when deflated.

Step 4: Deflate and Fold Properly—Avoid Creases and Tears

Now that your pool is clean, dry, and damage-free, it's time to deflate it. But deflating an inflatable swimming pool isn't as simple as just pulling out the plug and letting it flop. Doing it wrong can lead to creases, which over time can weaken the material, or even tears if you're not careful. So let's do this methodically.

First, open all the valves to release the air. If your pool has multiple chambers (like some larger models), deflate them one at a time—start with the top chamber, then work your way down. This helps prevent the pool from collapsing unevenly and stretching the seams. As the air escapes, gently press on the pool to push out trapped air—start from the edges and work your way toward the valves. You can also roll the pool (once it's partially deflated) to squeeze out air, but be gentle—don't use excessive force, which can damage the material.

Once the pool is fully deflated, it's time to fold it. Lay it flat on a clean, dry surface—avoid concrete or rough ground, which can have sharp pebbles or debris that might puncture the pool. Start by folding the sides in toward the center, like you're folding a large blanket. Then, roll the pool tightly from one end to the other, squeezing out any remaining air as you go. The key here is to fold it in a way that minimizes creases—try to align the edges and avoid sharp folds. If your pool came with a storage bag, place it in there; if not, use a large, clean plastic bin or a breathable fabric bag (avoid plastic bags that don't allow air circulation, which can trap moisture). Never store the pool folded in a way that puts pressure on weak spots, like near a repaired patch.

Step 5: Choose the Right Storage Location—Keep It Safe and Dry

Where you store your deflated pool is almost as important as how you prepare it. Winter brings cold, moisture, rodents, and pests—all of which can ruin your pool if you're not careful. So what's the ideal storage spot? Let's break it down.

First, temperature matters. Extreme cold can make the PVC material brittle, while extreme heat (like in an attic that gets hot in winter sunlight) can cause the material to degrade. The best spot is a cool, dry area with a consistent temperature—think a basement, garage, or closet. Avoid places that are prone to temperature swings, like unheated sheds or porches, or areas with high humidity, like a bathroom or laundry room (moisture is the enemy here). If you must store it in a garage, make sure it's off the floor (use a shelf or a pallet) to avoid water damage if the garage floods, and keep it away from any chemicals (like paint or gasoline) that might leak and damage the material.

Next, protect against pests. Mice, rats, and even insects love to nest in soft, cozy spots—and a folded pool looks like a perfect home to them. To deter pests, store the pool in a sealed plastic bin (with a tight-fitting lid) rather than a fabric bag. You can also place a few mothballs or cedar chips near the bin (but not directly on the pool, as the chemicals can transfer) to keep rodents away. If you're using a storage bag, make sure it's made of thick, pest-resistant material, and check it periodically for holes.

Finally, avoid heavy objects on top of the pool. Stacking boxes or tools on your folded pool can cause creases or even tears, especially if the material is cold and brittle. Give it its own space, even if it's just a corner of the garage—your pool will thank you.

Step 6: Use a Protective Cover—Extra Insurance Against the Elements

Even if you're storing your pool indoors, a little extra protection never hurts. That's where a cover comes in—and no, we're not talking about a random tarp you found in the shed. For maximum protection, consider using an inflatable pool cover tent or a specialized pool storage cover. Here's why:

An inflatable pool cover tent is designed to fit over your folded (or even partially inflated, if stored outdoors temporarily) pool and protect it from dust, moisture, and pests. Unlike a regular tarp, which can trap moisture if it's not breathable, many inflatable covers are made of waterproof, breathable material that allows air to circulate while keeping water out. They're also lightweight and easy to set up—just inflate the frame (if it has one) and place it over the pool. Plus, they add a layer of insulation, which can help protect the pool from extreme temperature swings in unheated storage areas.

If an inflatable pool cover tent isn't in your budget, a heavy-duty, breathable storage bag (like those made from canvas or polyester) works too. Just make sure it's large enough to fit your folded pool without squeezing it, and that it has ventilation holes to prevent moisture buildup. Avoid plastic tarps or garbage bags, which don't breathe and can trap condensation—remember, moisture is the enemy!

Step 7: Periodic Winter Checks—Don't Set It and Forget It

You've cleaned, drained, inspected, deflated, folded, and stored your pool—done, right? Not quite. Winter is long, and conditions in your storage area can change. A quick monthly check can help you catch issues before they become big problems. Here's what to look for:

First, check for moisture. Open the storage bin or bag and feel the pool—if it's damp, that means there's moisture inside, which could lead to mold. If you find moisture, take the pool out, wipe it down with a dry towel, and let it air out in a warm, dry area for a few hours before re-storing. Also, check the storage area for leaks or condensation—maybe a pipe dripped, or the humidity spiked. Fix the source of the moisture if you can (like using a dehumidifier in the basement).

Next, check for pests. Look for signs of mice or insects: chew marks, droppings, or nesting material. If you find any, remove the pool immediately, clean it thoroughly, and then take steps to pest-proof the area (like setting traps or sealing entry points). Finally, check the pool itself for any new damage—maybe a crease turned into a tear, or a patch came loose. Catching these issues early means you can fix them before they get worse.

These checks don't have to take long—10 minutes a month is enough. Think of it as a "pool wellness check" to make sure your summer companion is staying healthy until you meet again.
