Methods/Steps

1. First, empty the hot water in the thermos and add vinegar into the thermos, making sure the amount of vinegar just covers the bottom of the bottle (thermos).

2. Then put the stopper on the thermos, place the thermos horizontally, and then slowly rotate it so that the vinegar is in full contact with the wall of the thermos. Swirl for about 40 seconds, then uncork the bottle and pour out the vinegar.

3. Then fill the thermos one third of the way with water. Put the stopper on the bottle, pinch the stopper with your hand to leave a slight gap at the bottle mouth, and then shake the thermos. Shake the thermos for about 15 seconds and then pour out the water.

4. Observe if there is no scale in the thermos. Then repeat the previous step with clean water and wash twice more. If there is still a small amount of scale, repeat the second step with a small amount of vinegar to dissolve the scale. Then rinse it three times with clean water.
