Our automatic toilet cleaner contains detergents, brighteners and fragrances. It can maintain long-lasting and powerful descaling, deodorizing, antibacterial and residue-free effects, safely damage the glaze surface, and does not require frequent replacement, saving effort and providing comfort. Its usage method is very simple: 1. Unscrew the cover of the toilet cleaner (note that the aluminum film does not need to be peeled off. You can wear gloves to avoid contamination); 2. Place the base on top, the liquid at the bottom and screw it directly onto the base (be careful not to turn it upside down to prevent the liquid from flowing out). 3. Open the toilet lid and quickly put the toilet cleaner bottle into the water tank. 4. When you press the flush button, the toilet cleaner will automatically release for cleaning. It can effectively adjust the ph value, balance moisture, and leave a pleasant fragrance after use.
