How often do you clean hotel windows?

Every day, a cleaner cleans the room and cleans the glass.

Glass cleaning method: pour a little shampoo into the washbasin, stir it evenly, and dip it with a rag, which will make the glass door exceptionally clean and bright. Paint chalk, lime water or gypsum powder on the glass door in advance. After the glass is completely dried, wipe it directly with a dry rag to remove stains and clean the glass. For the old dirt accumulated in the corner of the glass door, you can mix it with half cold and half water during cleaning, put it in a watering can, spray it on the glass, and then gently wipe it with old newspapers.
