Sewage well and pipeline cleaning: Every quarter, the basement sewage well will be thoroughly cleaned, and the sewage pipeline will also be washed clean when flushing the ground.

Regular deep cleaning: Every month, use cleaning agents (such as stain removers, dishwashing liquid) to spread on the floor tiles, water them slightly, and thoroughly brush them with a long handled brush. After brushing, rinse with clean water until it is as clean as new, and gently wipe the wall base with a wet or dry towel to remove any contamination.

Cleaning standard: Glazed tiles should be visually clean, free of any stains, and able to clearly reflect the outline of the channel lighting. Vitrified floor tiles should be visually clean and thorough, free of debris and stains, and present the expected luster. For ordinary floor tiles, the goal is also to maintain a clean and stain free appearance when viewed visually.

Safety Notice: When using cleaning agents to scrub floor passages, special attention should be paid to avoiding corrosion of metal objects and elevator stainless steel hall doors.
