If you accidentally scratch the bathtub, but the scratch doesn't penetrate the surface, use dry or wet 1500# water mill sandpaper to polish it gently until it is smooth (the place where the sandpaper is polished must be kept wet), and then use a special compound called Meguiar's 10# mirror glaze (or wipe it with a wet rag after applying toothpaste). If the gloss cannot be restored, the surface can be polished with surface chemicals.
1, the scale on the surface can be cleaned with weak acid detergent, and it is recommended to wipe it with lemon cloth in a warm state.
2. After years of use, if you want to keep the surface bright, you can polish it with polishing agent to make it as bright as new.
3, thoroughly clean the acrylic surface after each cleaning, don't let the detergent into the circulation system.
4. Try to avoid spraying water directly on the lamp and computer panel in the product.
5. The steam room should regularly clean the scale in the steam engine, inject weak acid solution into the steam engine to heat the volatile acidity, shut down the machine to remove the moisture in the machine, and then rinse it with water.
6. When the hardness of water is too high, it is recommended to clean the hydraulic device every two years.
