Step 1: Rinse with warm water, the water temperature can be slightly warm to the touch. For the places where dirt is easily attached to the mouth or bottom, you can use a detergent to scrub, you can use a special cleaning cloth, the cleaning cloth is a polyester-cotton composite, which has good water absorption but can not lose hair, and absolutely avoid scratches;
Step 2: After rinsing, put the cup upside down on a flat cleaning cloth, let the water flow down naturally and control it to dry. When putting the cup upside down, be careful not to store water on the bottom of the cup, otherwise water marks will easily form;
Step 3: After the water in the cup is dry, wipe the water marks left with a dry cleaning cloth. When wiping, hold the cup with your left hand and wipe with your right hand. Start with the bottom, then the body, and finally the mouth. When wiping the inside of the cup body, the towel should be gently rotated around the cup body, do not wipe vigorously;
Step 4: After cleaning, the glass can be hung upside down on the cup holder without water marks, or it can be placed in the wine cabinet with the mouth up. Avoid putting the cup upside down in the wine cabinet for a long time, so that the unclean or stale smell will easily accumulate in the cup and bowl if it is not moved for a long time, which will affect the use.
