1. When cleaning, use a neutral detergent and a softer sponge or cloth.

2. The bathtub must be cleaned every week to ensure that it is kept dry after cleaning.

3. The dark-colored detergent that is easy to cause the pigment to penetrate the bathtub surface must be avoided.

4. Remember not to use things with strong abrasion ability, and high alkaline cleaning products cannot be used.

5. As long as you see a little bit of damage to the bathtub, you must tell the responsible party to repair it, otherwise the problem will worsen.

6. After each use, the water system must be turned off, otherwise the bathtub will accumulate water if the water drips frequently.
