How Do You Clean and Disinfect an Inflatable Hot Tub Cover?

An inflatable hot tub is all fun and relaxation (and a great deal) until the cover starts looking like it belongs in a swamp. If you've noticed grime, mildew, or a weird sticky film on your hot tub cover, it’s time for a deep clean.

Ignoring a dirty cover can lead to bacteria buildup, foul odors, and even damage to the material. Luckily, cleaning and disinfecting an inflatable hot tub cover is easy with the right approach. Let’s break it down step by step.

Why You Need to Clean Your Hot Tub Cover

An inflatable hot tub cover takes a beating. It's exposed to moisture, sun, dirt, and chemical residue. If you don’t clean it, you’re looking at mold, stains, and a cover that starts to fall apart way too soon. Keeping it clean means your water stays fresher, your cover lasts longer, and your hot tub doesn’t turn into a science experiment.

Step-by-Step Guide to Cleaning an Inflatable Hot Tub Cover

Step 1: Remove the Cover and Rinse It Down

Before using any cleaning solution, hose down the cover with fresh water. This helps remove loose dirt and dust. A light scrub with a soft brush can knock off surface grime.

Avoid high-pressure washers. The force can damage the seams and material.

Step 2: Use a Gentle Cleaning Solution

Most inflatable hot tub covers are made from vinyl or PVC, and harsh cleaners can break them down over time. Stick to something gentle.

DIY Hot Tub Cover Cleaner:

• One gallon of warm water
• One cup of white vinegar or mild dish soap
• One teaspoon of baking soda for extra scrubbing power (optional)

Use a soft sponge or microfiber cloth to wipe down the cover. Pay extra attention to any stained or grimy areas.

Avoid bleach, ammonia, or abrasive scrubbing pads. These can degrade the cover’s surface and weaken its structure.

Step 3: Disinfect the Cover to Kill Mold and Mildew

If your cover has mildew or a musty smell, it needs a deeper disinfecting clean.

• For light mildew: Mix equal parts white vinegar and water. Spray it directly onto the affected area and let it sit for ten minutes before wiping clean.
• For tough mold spots: Use AquaDoc's surface cleaner spray.
• For stubborn stains: A magic eraser can work wonders on scuffs and built-up grime without damaging the material.

Always rinse thoroughly after disinfecting to prevent residue from getting into your hot tub water.

Step 4: Dry Thoroughly Before Replacing

Never put a damp cover back on your hot tub. Lay it out in direct sunlight or in a well-ventilated area to dry completely. This helps prevent mold from coming back.

If your cover has an inner foam core, check for water absorption. If it’s heavy with trapped water, it may need replacing.

How to Protect and Maintain Your Hot Tub Cover

Now that your cover is clean, here’s how to keep it in top shape.

• Apply a UV protectant. Sun exposure can break down vinyl over time. A UV-blocking spray helps extend its lifespan.
• Keep water chemistry balanced. Over-chlorinated water can lead to chemical damage on the cover.
• Store it properly. If you’re not using your hot tub for a while, store the cover in a dry, shaded place.
• Clean monthly. A quick rinse and wipe-down once a month prevent major buildup.

When to Replace Your Inflatable Hot Tub Cover

If your cover is waterlogged, cracked, peeling, or has an odor that won’t go away, it might be time for a new one. No amount of cleaning will fix a cover that’s past its prime.
