When cleaning the inner wall of a spa jacuzzi tub, pay attention to the following: • Use cleaning tools made of suitable materials • Avoid using overly abrasive brushes • Wipe all surfaces evenly The inner wall is the area the user directly contacts, so cleaning it is especially important.

Generally, commonly used chemicals in spa jacuzzi tubs mainly include the following categories: • Disinfectants (such as chlorine or bromine) • Shock treatment agents (high-concentration oxidants) • pH adjusters • Alkalinity adjusters

In fact, the water in a spa jacuzzi tub usually does contain certain chemicals. These chemicals are not contaminants, but rather water treatment agents specifically added to ensure water safety and hygiene.

Under certain conditions, spa jacuzzi tubs can indeed develop mold. Especially when the device is not properly maintained or cleaned infrequently, mold is more likely to form inside or on the surface of the device.

Most modern spa jacuzzi tubs are equipped with dedicated filtration systems and filters, which play a crucial role in maintaining water cleanliness. Filters help remove impurities, particles, and some contaminants from the water, keeping it clear and reducing the accumulation of harmful substances.

High chlorine levels themselves do not directly cause spa jacuzzi tub water to turn yellow. Chlorine is an effective disinfectant. At normal or excessive doses, it does not directly produce yellow pigments or release compounds that turn water yellow.
