1. Put some paper scraps in the bottle, pour warm salt water and gently shake for a while to remove the scale.
2. Pour about 500 grams of baking soda with a concentration of 1% baking soda or heat vinegar into a bottle and gently shake the scale to remove it.
3. Break the two egg shells slightly, put them in the bottle, then fill the half tea jar with cold water, plug the cork, and hold the neck of the bottle mouth with one hand, and hold the bottom of the bottle with the other hand to rotate and shake up and down and left and right for about 20 seconds, remove the stopper and pour out the eggshell, and then wash it twice with clean water.
4. Take 200 grams of dilute hydrochloric acid and soak it in the bottle for a while, and then shake it to remove the scale in the bottle.
5. Pour boiling noodle water into the bottle, shake for a few minutes, and then rinse with clean water to clean.
6. Take some sunny leaves or pumpkin leaves, cut into 3 cm to 4 cm square size pieces, put them in the bottle, then add a little cold water, gently warm the water bottle, shake it a few times, pour it out, and then wash it with clean water.
7. Pour some vinegar in the kettle, gently brush with a soft bristle brush, to fully contact the rust with vinegar, if there is still stubborn, you can pour some hot water to continue brushing, after the rust completely disappears, rinse with clean water. The main component of rust is calcium carbonate, because it is insoluble in water, so it will be formed on the wall of the pot, vinegar has acetic acid, which can react with calcium carbonate to form salt that can be tolerated in water, so it can be washed off. However, because acetic acid is a weak acid, it will not be immediately visible, so you need to use tools, brushes or anything, or heat water to promote the reaction. Detergent and laundry detergents are alkaline and cannot reflect calcium carbonate, so they are ineffective and will harm the skin. Vinegar is a very weak acid and is diluted a lot, so it will not hurt the hands.
