How to remove scale in Glass Mug?

1: Vinegar effectively removes scale (tea scale) on the Glass Mug. Reason: The main component of scale is calcium carbonate. Using chemical reaction, there is acetic acid in vinegar. It can react with calcium carbonate to form water-soluble salt. Washed off easily.

2: After rubbing the Glass Mug (tea dirt) with salt, if there is dirt on the glass cup and glass jug, soak it in salt water for 10 minutes, and then dry it with salt, it will be clean soon.

3: Potatoes remove water scale (tea scale) on the Glass Mug. I bought potatoes at home, peeled the potatoes, and boiled the potato skins in a pot. After boiling the water, use this boiling potato chip water to clean the surface of the tea cup, so that the scale (tea scale) of the glass can be removed very easily.

4: Toothpaste can also quickly get rid of scale (tea scale), squeeze out the toothpaste and evenly apply the inner surface of the Glass Mug. Use a steel wire ball, toothbrush or a rag to repeatedly apply and clean the surface of the tea stain. Repeated scrubbing for three minutes, you find that the toothpaste has changed color, that is to say, the scale or tea scale has been removed, just rinse with clear.
