What Maintenance Does a Hot Tub Need?

Do hot tubs require a lot of maintenance?

When considering the purchase of a hot tub, one of the deciding factors is of course the amount of maintenance needed to keep it in optimal condition. At first thought, many people automatically assume that hot tubs require more maintenance than other types of tubs; however, this is not necessarily the case. Hot tubs can be amongst the least demanding types of household fixtures. They need just as much care and attention as most large appliances, but as long as your hot tub is properly looked after, it should last you for many years to come. The main maintenance required for a hot tub is keeping the water clean and balanced. This involves clearing any debris, regularly checking the temperature of the water, and testing the alkalinity and pH levels. This may sound complicated, but the process is made relatively straightforward with the right hot tub chemicals.

Owners must also make sure to drain their hot tub and replace the water at least every three months, as a chemical imbalance or bacteria growth can quickly become an issue. Common household products to clean and maintain a hot tub can also help take some of the stress out of maintenance.

Clean your hot tub weekly 

Weekly cleaning is the basic level of routine maintenance your hot tub needs. This includes brushing down the walls of the hot tub, particularly around the jets, to remove any lingering oils and germs on the surface. Vacuuming the bottom of the hot tub is also important to remove any dead skin cells or dirt. Additionally, it’s important to skim the surface of the water regularly before draining to avoid any debris such as leaves or insects, from entering the hot tub’s filtration system. This helps keep the hot tub running smoothly and efficiently, balancing out its pH.  

Drain and refill your hot tub quarterly

It’s recommended that the water in your hot tub be drained and refilled every three months or so. This allows for a thorough clean of the interior surfaces, as well as a new batch of clean, hot tub-friendly water. It also gives owners the opportunity to check any filters and ensure there is no calcium build-up on the surfaces of the hot tub itself. When draining the hot tub water, be sure to use a chemical-safe hose to avoid introducing dirt or rust into the hot tub. 

Sanitising your water

One of the most important steps in keeping a hot tub clean is sanitising the water. This involves using special hot tub chemicals such as chlorine or bromine in order to eliminate bacteria and other organisms from the hot tub water. It’s best to test your water regularly to make sure that it is safe and healthy for all users. It’s also important to use a specialised hot tub sanitiser that best meets your individual needs, such as chlorine tablets or granules. This will help ensure that your hot tub and its filters remain free from bacteria, fungi, and other unwanted elements. 

In conclusion, hot tubs do require some amount of regular maintenance to keep them running smoothly and safely. However, the level of upkeep can be kept to a minimum by performing the necessary weekly and quarterly cleaning tasks, while also using the right chemicals to sanitise the hot tub's water.

Common household products to use to clean a hot tub

Olive Oil for Gunk

If you encounter any sticky residue or gunk on the surface of your hot tub, olive oil can be a handy solution. Simply pour a small amount of olive oil onto a soft cloth and gently rub the affected area. The oil helps break down the gunk. However, it is crucial to wash off the oil with mild soap and water afterwards to prevent any oil residue from entering the hot tub water and potentially causing issues with the filter.

Diluted Bleach

Diluted bleach is a powerful cleaner and sanitiser that can effectively remove scum lines and tough stains from your hot tub shell. For this method, make sure to wear rubber gloves for protection. Mix bleach with ten parts of water to create a diluted bleach solution. Carefully wipe down the spa shell with the solution, paying extra attention to problem areas. Once done, rinse the shell thoroughly to remove any remaining bleach residue. It's important to note that bleach should never be mixed with other substances, as it can create hazardous chemical reactions.

Bleach can also be used to clean the underside of your hot tub cover. However, be aware that it can be harsh on vinyl over time. Wipe down the cover with the diluted bleach solution and allow it to sit for a few minutes if mildew is present. Rinse the cover thoroughly afterwards.

Baking Soda

Baking soda is a versatile and gentle abrasive that can effectively clean scum lines and stains in your hot tub. Create a paste by mixing baking soda with water, then apply the paste to a damp cloth. Gently rub the scum or stains with the cloth until they are removed. Rinse the area with water to remove any baking soda residue.
