Black Mold in Hot Tub: How to Get Rid of Them? (Explained)

A hot tub can be a fun and relaxing way to spend a summer day, but it can also cause discomfort and irritation.

You may have black mold in your hot tub if it isn’t staying clean. Learn how to remove black mold from your hot tub so you can enjoy the pool season worry-free.

What causes black mold in the hot tub?

The causes of black mold in the hot tub include the fungus Trichothecene, poor ventilation, water damage, and excessive humidity. Additionally, poor ventilation and poor air quality also contribute to black mold growth in hot tubs. Not enough sunlight and cleaning also contribute to this.

Trichothecene is also produced when fungal spores find their way into water sources or hot tubs. When inhaled, the fungus can cause serious health problems. It thrives in moist environments. The mold in the hot tub may be caused by the following reasons:

The fungus Trichothecene:

Trichothecene fungus causes black spots on inanimate objects and the skin. Most commonly, it grows in wet environments like hot tubs, but it can also grow in other places with high humidity.

Black mold growth inside or outside your hot tub can be a sign of serious health problems, so make sure you have it cleaned right away.

Humidity:

Humidity plays a major role in the growth of black mold in hot tubs. The fungus Trichothecene thrives in high humidity, and it’s especially dangerous for people who are vulnerable to it.

Try lowering the humidity level in your hot tub or switching to a humidifier if you are experiencing black mold symptoms.

Poor ventilation:

When there is insufficient ventilation in your hot tub, black mold can thrive.

Due to poor air circulation, aromas from plants and chemicals used to maintain the pool are concentrated in one area, which is ideal for black mold growth.

Insufficient air quality:

Poor air quality is another cause of black mold growth in hot tubs. Particles and gases can seep into the water, allowing mold to grow unchecked.

It may be time to clean your hot tub thoroughly if you notice an increase in black spots on its surface.

Lack of sunlight:

A lack of sunlight is conducive to the growth of black mold. In a dark corner, your hot tub’s water can become conducive to its growth.

It may be worth investing in a lighting system that will brighten up your pool area if this is the case for you.

Where can you find black mold in the hot tub?

There are many different areas in a hot tub where black mold can grow. On the water’s surface, inside the spa area, and even on nearby objects, it can grow. Black mold growth in your hot tub should be addressed as soon as possible.

Mold around hot tub:

You are most likely to find black mold in a round hot tub. The bacteria can grow on the surface of the water, inside the spa area, or on nearby objects.

It may be time to thoroughly clean your hot tub if you see an increase in black spots on its surface.

Mold growing from light fixture:

Remember that mold can grow around and underneath the bulbs in your hot tub if it has a light fixture above it.

Ingesting this type of fungus can cause black spots on your skin and on objects. These fungi thrive in environments with little sunlight.

Mold on hot tub pillow:

You need to clean your hot tub pillow as soon as you notice black mold growing on it. A fungus of this type can result in serious health problems if ingested, and can also spread rapidly indoors.

Mold on hot tub filter:

It may be time to replace your hot tub filter if you notice black mold growing on it.

When ingested, black mold releases toxins that can cause serious health problems. Furthermore, black mold can spread rapidly indoors.

How to get rid of black mold in the hot tub?

For the removal of black mold from a hot tub, you should use a hot tub cleaner followed by boiling water. You can try using a vacuum cleaner equipped with a hose attachment. The use of a commercial cleaner is also effective in eliminating black mold from hot tubs.

The following are some of the most common methods:

Use a hot tub cleaner:

Several hot tub cleaners are specifically designed to remove black mold from wet surfaces.

Pour the cleaner into the spa area and wait until it is fully absorbed before cleaning. After using any chemicals, be sure to rinse them off.

Pour boiling water over mold:

Pour boiling water over black mold growing on your spa (but don’t scald yourself). In many cases, this method is effective in destroying mold colonies.

Use a vacuum cleaner with the hose attachment:

Try using a vacuum cleaner with the hose attachment instead of a hot tub cleaner.

When cleaning around water jets and prop shafts, take caution – these areas can be very dangerous if not handled properly.

Mix a solution of bleach and water:

The most common way to remove black mold is to mix 10 percent bleach with 90 percent water. Spray the solution onto the mold using a spray bottle. After using the product, rinse it off with water.

Use a commercial cleaner:

A commercial mold removal product can help if none of the methods above work.

Take appropriate precautions before using – some cleaners can be very dangerous if not used correctly. After using any of these methods, be sure to thoroughly clean your hot tub – black mold can easily spread.

Is black mold in the hot tub dangerous?

It is very dangerous if black mold forms inside a hot tub. Black mold produces toxic elements that can cause respiratory problems, eye irritations, and skin infections.

It is known that black mold can cause a wide range of health problems. Among these are allergic reactions, toxic shock syndrome (TSS), respiratory issues, and brain fog. This toxin can even cause death if inhaled.

Be sure to clean your hot tub as soon as you notice black mold and take appropriate precautions.

In addition, you should inform your hot tub manufacturer if you see any signs of black mold. Contaminated hot tubs often have defective parts, which can lead to serious problems.

How to prevent black mold in the hot tub?

Regularly cleaning your hot tub and taking proper precautions when cleaning it will prevent black mold from growing. Hot tub back mold can be prevented by following these steps:

Proper sanitizer amount:

Make sure that you use enough sanitizer in the hot tub to prevent the growth of black mold.

Not overloading the filter:

You can also prevent black mold in the hot tub by not overloading the filter. By overloading the filter, debris and other pollutants can build up, which can lead to black mold growth.

Don’t overuse chlorine or bromine in the spa after you’ve used it, and make sure you rinse all the water off.

Regularly checking for leaks:

Checking for leaks is another way to keep your hot tub clean and free from black mold. Immediately contact your hot tub manufacturer if you notice any signs of a leak.

A regular cleaning of the hot tub can prevent the growth of black mold in the future.

Make sure that your filters are not overloaded and that you use a good sanitizer to prevent debris buildup and black mold growth in your home.
