First spread baking soda evenly in the place behind the scale inside the bucket, and then gently scrub it with a wet sponge with rare water.
2, cooking vinegar method:
Connect the bucket to two-thirds of the bucket, and then add one-third of the vinegar. Then add hot water and let it stand for 7-8 minutes. After that, pour out the water and leave only half of it to cool naturally. After cooling, scrub the inside with a sponge or rag. If the scale is very thick, use this method again, then leave it under natural conditions for one night and then scrub it the next day.
3, fruit cleaning method:
We can also cut the lemon into small pieces or juice it, pour it into a bucket, then add water to two-thirds of the bucket, add hot water as well, and then stand still for about 1 hour; Then gently rub the inside with your hands, then pour out the water, then add the same hot water and let it stand for about 15 minutes, and the scale will disappear after pouring out.
Extended data:
Harm of scale
1, scale has poor thermal conductivity, which will lead to the deterioration of heat transfer on the heating surface, thus wasting fuel or electricity.
2. If scale adheres to the heating surface of thermal equipment, it will endanger the safe and economical operation of thermal equipment. Because the thermal conductivity of scale is poor, it hinders heat transfer. The heat absorbed by the furnace tube from the flame side can not be well transferred to the water supply, and the cooling of the furnace tube is affected, so that the wall temperature rises, causing the furnace tube to bulge and cause tube explosion.
3. When the scale is cemented, a large number of heavy metal ions are often attached. If the container is used to hold drinking water, there is a risk that heavy metal ions will be dissolved in drinking water too much.
4. When scale fragments enter the stomach, they will react with hydrochloric acid, releasing calcium and magnesium ions and carbon dioxide. The former is the necessary substance for stone formation. The latter will make people flatulent and uncomfortable, and patients with gastric ulcer may also have the risk of gastric perforation.
