Common Types of Stains on Inflatable Hot Tubs

Inflatable hot tubs are a great way to relax, but unfortunately can become stained with use. There are many different types of stains that can appear, often caused by a combination of factors such as body oils and lotions, pool chemicals, dirt and debris, hard water minerals, and even rust. Let’s take a look at the most common types of stains and how to remove them.

Mildew and Dirt Stains: Mildew forms when chlorine levels in the water are too low, as can be caused by high levels of dirt and debris. These stains are often black in color, but can also appear green or grey. To remove mildew and other dirt stains, use a soft brush and a solution of one part bleach to four parts water directly on the stain. Let it sit for 30 minutes and rinse the solution away with warm water.

Oil, Lotion or Cosmetics Stains: Oil, lotions, and other cosmetics such as sunscreen, sweat and hair products, can leave behind white, milky or yellowish stains on the fabric of your hot tub. To remove these, use a solution of two parts water to one part vinegar or a mild soap solution directly on the stain. Let it sit for 30 minutes, then rinse the solution away with warm water.

Rust, Hard Water, and Metal Stains: Rust, hard water, and metals can leave behind red, brown or orange stains on the fabric of your hot tub. To remove these, sprinkle a natural cleaning powder over the affected area and let it sit for up to an hour. Then, scrub away the stain with a soft brush before rinsing the powder off with warm water.

Avoiding Future Stains: The best way to avoid stains is to keep your hot tub clean, and to drain and clean it regularly with a mild soap solution. For extra protection, you can also use a stain inhibitor, and cover the tub when not in use. This will help protect against staining caused by water, sunlight, and other factors.

Removing Mildew and Dirt Stains from Inflatable Hot Tubs

Mildew and dirt stains can be a common problem on inflatable hot tubs. To remove these stains, it is important to use a gentle cleaning solution that will not harm the hot tub material. Here are some of the common solutions used to remove mildew and dirt stains from inflatable hot tubs:

• Bleach and Water: Mix one part bleach to 14 parts water and use a cloth to wipe the area that needs to be cleaned.

• Vinegar and Water: Mix one part vinegar to two parts water and use a cloth to wipe the area that needs to be cleaned.

• Natural Cleaning Powder: Look for a natural cleaning powder that is specifically designed for hot tubs. Be sure to check the label for safe and effective use.

In addition to using the correct cleaning solution, it is also important to clean the hot tub regularly. Regular cleaning will help reduce the number of dirt and mildew stains that accumulate on the hot tub. After cleaning, it is important to rinse the tub with clean water to ensure all cleaning residue is removed.

Getting Rid of Oil, Lotion or Cosmetics Stains

Oil, lotion and cosmetics can be some of the most stubborn stains on inflatable hot tubs. It is important to act fast when you find a spill of lotion, oils or cosmetics and use a cleaning solution to eliminate the stain. Here are some easy steps to get rid of those stains:

1. Soak up the spill with a paper towel or fabric, taking care not to spread it around.
2. Create a cleaning solution of two parts water, one part vinegar and one part dish soap.
3. Dip a soft cloth in the solution and dab the stain gently until it is eradicated.
4. Rinse the area with clean water and dry it with a soft cloth.

If the stain persists, you can try using a cleaning powder or solution specifically designed for inflatable hot tubs. These products can be found at most pool, hot tub and spa supply stores. Before using any chemical, be sure to read the label and follow directions for safe usage.

For extra stubborn stains, create a paste of baking soda and water and apply it to the stained area. Allow it to sit for at least fifteen minutes before wiping away any excess with a microfiber cloth. Always make sure to rinse the area with clean water and dry it with a soft cloth to avoid any residue remaining.

Finally, you can use a gentle scrub brush to safely remove any remaining stains or residue.

By following these tips and taking care when using lotion, oil and cosmetics around your inflatable hot tub, you can prevent and remove stains to maintain its condition and keep it looking its best.

Removing Rust, Hard Water and Metal Stains

Removing rust, hard water and metal stains from inflatable hot tubs can be difficult, but a few simple steps can help. Start by cleaning with a mild detergent, then use a rust remover to break down the stains and make them easier to remove. Once the stains are gone, use a metal cleaner to prevent the stains from returning.

Below is a list of supplies that you will need to remove rust, hard water and metal stains:

• Mild detergent
• Rust remover

To remove the stains, start by using a mild detergent to scrub away the surface dirt, then apply a rust remover according to the directions.

Once the stains are removed, use a metal cleaner to help prevent future stains from forming. Finally, rinse the area with clean water and dry with a clean cloth.

By following these steps and using the right supplies, you’ll be able to easily remove rust, hard water and metal stains from your inflatable hot tub. With regular maintenance and proper care, you can also help prevent new stains from forming.

Avoiding Future Stains on Inflatable Hot Tubs

Stains can be easily avoided in the future by taking a few simple steps to keep your inflatable hot tub clean and well maintained.

  • Regular Cleaning: Regularly cleaning and draining your inflatable hot tub helps to prevent stains and mildew from forming. Use a diluted solution of bleach and water to disinfect the surfaces, and be sure to rinse them off afterward using clean, clear water. Empty and refill the hot tub regularly to keep the water clean and free of contaminants.
  • Paint and Stain Inhibitor: Once the hot tub is clean and dry, apply a paint and stain inhibitor to help repel oils, lotions, and other contaminants. This will help protect the hot tub’s surface from damage, fading, and staining.
  • Cleaning Procedures: After each use, it’s important to clean according to the manufacturer’s instructions to ensure the hot tub’s longevity. This includes wiping away any dirt, debris, and oils, as well as scrubbing any areas that may be prone to staining. Regularly cleaning the surfaces helps to prevent any unsightly stains from forming in the future.
  • Chemicals: Balancing your hot tub’s chemicals helps to prevent corrosion, cloudiness, and staining. Regularly test and adjust your pH levels, chlorine, and other stabilizers to keep your water clean, clear, and stain-free.

By following these precautions, you can help ensure that your inflatable hot tub stays stain-free and in pristine condition.


In conclusion, removing stains from inflatable hot tubs can be done with the right tools and cleaning solutions. Mildew, dirt, oil, lotion, rust, hard water and metal stains can all be safely and effectively removed.
