When you have a hot tub, you can keep track of important details like water cleanliness and the chemicals in the water. Taking care of your spa is critical to its longevity. In addition to regular hot tub maintenance, you'll need to know the basics of cleaning your spa in order to keep it in tip-top shape.
Sanitize the hot tub
Keep the water clean with chlorine or bromine. These chemicals will help kill bacteria and keep the water clear. Much like chlorinating a pool, you can use a floating chlorine dispenser that holds chlorine or bromine tablets that sanitize the water. These containers are slightly smaller than pool dispensers to accommodate the smaller size of a hot tub. Make sure to check the dispenser regularly so you can ensure there is always chlorine or bromine in the water.
Shock the water weekly
Shocking is a process of heavily chlorinating water with a larger-than-normal amount of chlorine to remove impurities in the water and ensure that the chemicals destroy the bacteria. This process can clear up cloudy water and kill organic matter in the water. When you shock a hot tub, it may help to dissolve the shock in water before adding it to the spa. For the best results, follow the instructions on the package.
Clean the filter regularly
Because the filter can quickly fill with dirt, oils and more, you'll want to rinse the filter weekly or bi-weekly. You should also complete a bi-weekly or monthly deep-cleaning process. To do this, you'll want to remove the filter and soak it in a filter cleaning solution that removes oil and residue to ensure that your filter is cleaned properly without damage.
Drain the tub every few months
Depending on how many people are using the hot tub in a given time frame and how often the spa is used, you should empty it completely on a regular basis. Draining the unit will remove any salts, oil remnants and other impurities in the water. When you drain the tub, you should also flush the filtration system to remove excess buildup in the system. Follow the manufacturer's guidelines to ensure this procedure is done correctly for your hot tub. While the spa is empty, scrub the shell to clean any residue or grime off the walls, seats and floor of your hot tub for a complete deep clean.
