Inflatable waterslides are a great addition to any backyard, especially during the hot summer months. However, they can also be a breeding ground for mold if not properly cleaned and maintained. Mold not only looks unsightly but can also pose health risks. In this guide, we’ll walk you through the process of effectively cleaning mold off an inflatable waterslide like a pro.

Understanding Mold and Its Effects

What is Mold?

Mold is a type of fungus that thrives in damp and humid environments. It reproduces by releasing spores into the air, which can then land on surfaces and start to grow. Mold can appear in a variety of colors, including black, white, orange, green, or purple.

When it comes to inflatable waterslides, mold can form when the slide is stored away while still damp or if water is allowed to sit on it for extended periods. The folds and crevices of the slide can create the perfect environment for mold to grow.

Health Risks Associated with Mold

Exposure to mold can lead to a variety of health issues, especially for individuals with allergies or asthma. Some common symptoms of mold exposure include sneezing, runny or stuffy nose, coughing, itchy eyes, throat, or skin, and watery eyes.

Long-term exposure to mold can lead to more serious health problems, such as respiratory infections and development or worsening of asthma symptoms. Therefore, it’s crucial to clean mold off an inflatable waterslide as soon as you notice it.

Materials Needed for Cleaning Mold

Before you start the cleaning process, gather all the necessary materials. Having everything at hand will make the process smoother and more efficient. Here’s what you’ll need:

  • A soft brush or sponge
  • A bucket
  • Warm water
  • Mild detergent
  • White vinegar or a commercial mold remover
  • A garden hose
  • Towels for drying

Step-by-Step Guide to Cleaning Mold off an Inflatable Waterslide

Step 1: Set Up the Inflatable Waterslide

Start by setting up your inflatable waterslide in a clean, open area. Make sure it’s fully inflated and ensure that all areas are accessible for cleaning.

It’s best to do this on a sunny day, as the sun’s ultraviolet rays can help kill mold spores. However, avoid doing this in extreme heat as it can damage the material of the slide.

Step 2: Prepare Your Cleaning Solution

In a bucket, mix warm water with a mild detergent. For every gallon of water, use about a cup of detergent. If you’re dealing with stubborn mold, you can add a cup of white vinegar to the mix. Vinegar is a natural disinfectant that can kill up to 82% of mold species.

If you prefer, you can use a commercial mold remover. Just be sure to follow the manufacturer’s instructions on the label.

Step 3: Scrub the Mold Off

Using a soft brush or sponge, scrub the mold off the inflatable waterslide. Be gentle to avoid damaging the material. Pay special attention to crevices and folds where mold can hide.

After scrubbing, rinse the area thoroughly with a garden hose. Make sure all the cleaning solution and mold is washed off.

Step 4: Dry the Inflatable Waterslide

Once you’ve cleaned the slide, it’s important to dry it thoroughly. Any remaining moisture can lead to more mold growth. Use towels to wipe down the slide, then leave it out in the sun to dry completely.

Make sure the slide is completely dry before storing it away. If possible, store it in a dry, ventilated area to prevent future mold growth.

Preventing Future Mold Growth

Prevention is always better than cure. Here are some tips to prevent future mold growth on your inflatable waterslide:

  • Always dry the slide thoroughly before storing it away.
  • Store the slide in a dry, ventilated area.
  • Regularly clean the slide, even if you don’t see any visible mold.
  • Consider using a mold-resistant spray on the slide.


Cleaning mold off an inflatable waterslide may seem like a daunting task, but with the right materials and techniques, it can be done effectively. Remember, the key to preventing mold growth is proper maintenance and storage. By following these steps, you can ensure your inflatable waterslide remains clean and safe for everyone to enjoy.
