What is a Hot Tub Scale?

Before we talk about the best solutions for hot tub scaling, let’s first define what exactly a scale is.

Scale refers to a mineral-based build-up. There are four main types of hot tub scaling – barium sulfate, calcium phosphate, calcium sulfate, and calcium carbonate.

Using hard water causes the unsightly flakes on the hot tub, which can also clog plumbing. Even if you have the best hot tub, when water is not balanced and if you don’t maintain the tub properly, scaling can be an issue. While it is often an indication of calcium build-up, the scale can also be a sign of white water molds in a hot tub.

Preventing Hot Tub Scale

Prevention is better than cure, even when it comes to hot tub scaling. That said, below are some of the best preventive measures.

1. Balance Water

You must learn how to balance pH in a hot tub if you want to prevent scaling. If the pH is too high, scales can start to form. Bring it down to an acceptable level to prevent the hardness of the water in your hot tub. Adding chemicals in the water, such as sodium bisulfate, is one of the easiest solutions. This can also be a promising solution if you want to fix a cloudy hot tub.

2. Keep the Filter Clean

Your filter could also be the culprit for the formation of the hot tub scale. Your hot tub filter cartridges have an important role in maintaining the quality of water. When the filters don’t function properly, the water can cause scales. It is important to clean hot tub filters regularly or replace them when needed.

3. Use a Scale Preventer

Removing and preventing hot tub scaling will be easy with the products that are available on the market. Some hot tub manufacturers may offer their versions of a scale preventer. Apply these products regularly as instructed.

Removing Hot Tub Scale

There are some instances when it is too late. The flakes are already there. However, this isn’t a hopeless case. With time and effort to spare, below are some of the best solutions.

1. Use a Vinegar Scrub

Vinegar is an all-around house cleaner that can also be promising when it comes to hot tub scaling. First, drain the hot tub and use a dry towel to wipe the surface. Mix one-part vinegar and one-part distilled water. Put it in a spray bottle and spray on the hot tub, especially on the part where you can see the scale. Let it sit for about five minutes. Scrub with a nylon brush, rinse, and dry. Do not use harsh abrasives or stiff brushes because they can damage the shell of the hot tub.

2. Use Bleach and Dishwasher

Fill the tub with water just slightly above the opening of the jets. Add half cup of dishwasher detergent and one cup of bleach. Turn on the hot tub jets. Drain the water. Fill the tub with water and wait for 15 minutes. Drain and wipe the surface to get rid of any residue. This will also work if you want to get rid of yellow algae in a hot tub.
