What is Mould?

Mould is a type of fungus that can form on a variety of surfaces, including hot tubs.

It’s caused by high levels of humidity and moisture, and often appears as a slimy, dark-colored substance.

In some cases, mould can even cause a musty smell.

Mould can be dangerous to humans as it can cause allergic reactions, asthma attacks, and other respiratory issues.

Therefore, it’s important to get rid of mould before it has the chance to spread and cause health problems.

How Does Mould Form in Hot Tubs?

Mould can easily form in hot tubs due to the combination of warm temperatures, high humidity, and moisture from peoples bodies.

The ideal environment for mould growth is a warm, moist environment, which is why hot tubs are particularly susceptible.

The combination of the hot water and humidity creates an ideal environment for mould to flourish.

Additionally, the chemicals used to clean and sanitize the hot tub can create a favorable environment for mould growth.

Without regular maintenance and treatment, mould can quickly and easily take hold in a hot tub.

Draining the Tub & Removing Debris

When it comes to removing mould from a hot tub, the first step is to drain the tub and remove any debris.

This will allow you to have full access to the mould and also make it easier to work on the affected area.

To drain the tub, you will need to turn off the hot tub and disconnect the hose from the filter.

Then, turn the drain valve to the open position and allow the water to flow out.

Once the hot tub is emptied, you can then remove any debris such as leaves, dirt, and other contaminants.

After that, you can begin the process of removing the mould.

Scrubbing with a Bleach & Water Mixture

Mould build-up in hot tubs is a common problem for many hot tub owners, but fortunately, it’s possible to get rid of mould without too much hassle.

One of the most effective methods for getting rid of mould from a hot tub is to use a mixture of bleach and water to scrub away the mould.

Before getting started, it’s important to drain the tub and remove any debris, as this will help create a clean surface for the bleach to work on.

When it comes to creating the mixture, it’s best to use a solution of one cup of bleach to every gallon of water.

Once the mixture is ready, it can be applied to the affected areas with a sponge or cloth.

Make sure to apply the solution evenly and let it sit for a few minutes before scrubbing it in.

When scrubbing, it’s important to use a gentle motion and avoid using anything abrasive, as this may end up damaging the surface of the hot tub.

Once the mould is gone, it’s important to rinse the area thoroughly to remove any remaining bleach residue.

Make sure to also refill the hot tub with clean water and add a new chlorine tablet to ensure the tub remains clean and free of mould.

Consider Using a Commercial Mould Cleaner

If the mould build-up in your hot tub is particularly stubborn, consider using a commercial mould cleaner.

Commercial mould cleaners are specifically designed to break down mould and mildew, making them more effective than homemade solutions.

When using a commercial mould cleaner, its important to read the instructions carefully and follow the directions precisely.

Start by diluting the cleaner according to the instructions.

Once youve mixed the cleaner, apply it to the affected area using a sponge or brush.

Be sure to wear gloves and protective eyewear to avoid contact with the cleaner.

Let the cleaner sit on the affected area for the recommended amount of time, then rinse it away with a garden hose.

Once the mould is gone, refill the hot tub with clean water and add a new chlorine tablet to ensure the tub remains clean and free of mould.

Refilling the Hot Tub with Clean Water

Refilling the hot tub with clean water is an important step in getting rid of mould.

After draining the tub and removing any debris, it is essential to refill it with clean water to ensure that all traces of the mould are gone.

This can be done by connecting a hose to the tubs inlet valve and turning the tap on.

As the water is filling the tub, it is important to check the chlorine levels and pH balance to make sure they are within a safe range.

Depending on the size of the tub, it may take several hours for it to fill completely.

Once the tub is full, it is important to add a new chlorine tablet.

This will help to keep the water clean and free of mould.

Additionally, it is important to regularly check the chlorine levels and pH balance to make sure they remain within a safe range.

If needed, make sure to add more chlorine tablets as needed.

Additionally, it is important to make sure that the tub has proper ventilation and that the filters are regularly cleaned to help keep the water clean.

By following these simple steps, hot tub owners can ensure that their tub remains free of mould and that the water remains clean and safe for use.

Refilling the hot tub with clean water is an essential step in getting rid of mould and should not be overlooked.

With a little bit of effort and regular maintenance, hot tub owners can keep their tubs free of mould and enjoy their hot tubs year-round.

Adding a New Chlorine Tablet

When it comes to keeping your hot tub clean and free of mould, one of the last steps is to add a new chlorine tablet.

Chlorine is an important chemical for keeping pool and hot tubs free of bacteria and other contaminants, and adding a new chlorine tablet can help ensure that the water remains clean and free of mould.

Its important to follow the manufacturers instructions for the tablet, as the dosage can vary depending on the size and type of hot tub.

Generally, youll want to place one tablet in the hot tubs skimmer basket, and add another to the floating dispenser.

The chlorine tablet will slowly dissolve in the water, releasing chlorine over time to keep the water clean and free of mould.

Additionally, you may want to add a granular chlorine shock periodically to ensure the chlorine levels remain consistent.

Make sure to monitor the chlorine levels regularly to ensure they are within the recommended range.

Its also important to remember that chlorine can be corrosive, so youll want to be sure to rinse the area thoroughly after adding the tablet.

This will help ensure that any residual chlorine doesnt damage the surface of the hot tub.

Additionally, you may want to consider investing in a chlorine test kit to ensure that the chlorine levels remain within the recommended range.

By following these steps, you can help ensure your hot tub remains clean and free of mould.
