1. Wipe the glass with toothpaste
Toothpaste contains abrasives. It is most suitable for brushing glass cups and the like. It will not damage the enamel layer and can also clean the stains. Find an unused toothbrush, connect the brush to the toothbrush handle, and bake it over a fire. Then bend it to ninety degrees and use it specifically to brush the bottom of the cup. Of course, is it better to buy a brush and use some toothpaste? Any brand will do. If it is specifically used for brushing, it is recommended to buy cheap toothpaste, which has large abrasive particles. Very useful!
2. Wipe the glass with salt
If there is dirt on the glass or glass jug, if you soak it in salt water for 10 minutes, then dry it with salt, it will be clean soon. If there are stains on the spout, you can cover the spout with wet salt overnight, and wash it with hot water the next day, it will be very clean. It is also very convenient to clean. If soaked in salt water for a few hours, the tea scale will fall off on its own!
3. Wipe the glass with vinegar
Glass cups and glass plates have accumulated dirt, so they can be easily washed with vinegar.
Tips: After washing the glass, put it upside down on a dry towel. After the glass is dry, it will not leave water marks.
