What are the water ladles provided in hotel rooms used for?

These are items needed by housekeeping staff to clean the bathroom.

To wash the bathtub and shower room, first dip a vegetable cloth in detergent, gently scrub the shower head, faucet, water temperature regulator, water plug and chain, etc., and check whether the drainage is normal and the water quality is good. Use detergent to scrub the bath walls, shower doors, soap dishes, handrails and bathtubs, outside the shower room and in corners. Pay special attention to the upper end of the bath wall where grease and soap foam are likely to accumulate. Then fill the washbasin with water, use a ladle to hold the clean water in the washbasin, and rinse it along the bath wall and around the bathtub. It must be bright and leave no traces of oil stains. After washing, turn down the middle faucet to prevent guests from washing their heads when they turn on the faucet. .
