II. How to clean toilet bowls in bathrooms
1、Clean the urinal
Uranals are typically made of ceramic, offering a smooth surface that resists staining. However, over time, they may still accumulate water or urine stains. These can be cleaned with brushes or sponges and a mild cleaning solution mixed with lukewarm or cold water. During cleaning, pay particular attention to the edges of the drain and the area beneath the trap, as these are prone to trapping dirt and debris. Additionally, ensure the drain is kept clear of any obstructions to prevent clogging.
2、Maintenance of urinals
Please do not strike or step on the urinals. Please gently wipe the ceramic urinals with clean water only. Do not use cleaning agents, solvents, or abrasive products with strong acidity or alkalinity, as these may damage the surface and accessories. Do not use hot water to clean the porcelain fixtures. Do not dispose of paper towels or other waste materials into the urinals, as this may cause blockages.
