Owning a spa or hot tub is a long-term investment in relaxation and wellness, but keeping it in top condition requires proper care. One of the most overlooked aspects of hot tub ownership is spa cover maintenance. A well-maintained cover not only protects your investment but also improves energy efficiency, prevents damage, and extends the life of your spa.
For Twin Cities spa owners, these six essential tips will help your hot tub cover stay durable, functional, and looking great year-round, no matter Minnesota’s hot summers or icy winters.
1. Clean Your Spa Cover Regularly – Inside & Out
Dirt, debris, and grime can accumulate on your hot tub cover, causing wear and shortening its lifespan. Keeping your cover clean is the first step in long-term hot tub maintenance.
Tip: Use mild soap and water with a soft brush or sponge to clean the exterior monthly. For the underside, rinse with a gentle stream of water and scrub lightly to remove any buildup. Always let your cover air dry completely to prevent mold and mildew.
Winter Tip: Snow can add significant weight, causing wear or warping. Remove snow promptly using a soft broom to avoid damaging the cover.
2. Apply a Vinyl Protectant Spray to Shield Against UV Damage
Minnesota summers bring beautiful sunshine but strong UV rays can cause fading, cracking, and premature wear on spa covers. Protect your hot tub cover by applying a vinyl protectant designed for spa covers every 2–3 months.
Tip: Position your spa in a shaded area or under a gazebo or hot tub enclosure to reduce sun exposure. This also helps prevent your cover from drying out or warping.
3. Keep Your Spa Cover Secure
Strong winds or heavy snow can damage an unsecured cover. Make sure your spa cover is always properly fastened with straps or a cover lift.
Pro Tip: A high-quality cover lift makes it easier to remove and replace the cover without unnecessary stress, while also protecting the edges from damage.
4. Keep Kids, Pets, & Guests Off the Cover
Even durable spa covers aren’t designed to hold the weight of children, pets, or guests. The center of the cover is typically the weakest point.
Tip: Place your spa in a location where children and pets cannot access it easily, or use a gazebo to minimize the risk of damage.
5. Seasonal Maintenance & Airing Out
Seasonal maintenance is crucial in Minnesota. During spring or fall, take advantage of dry days to air out your cover. This removes trapped moisture and reduces the risk of mold or mildew.
Tip: Spray a mild chlorine solution on the underside during regular cleaning. Clean thoroughly before winter to prepare your cover for the cold season.
When to Replace Your Hot Tub Cover
Even with the best care, spa covers eventually wear out. Signs your cover may need replacement include:
- Cracks or tears in the vinyl
- Waterlogged foam core
- Mold or mildew that cannot be removed
- Warping or sagging
- Losing heat
Cal Spas offers durable replacement covers made with marine-grade vinyl, reinforced steel, and dense foam cores; perfectly suited for Minnesota’s climate.
