In order to save money, many people will add water to dilute the dishwasher or hand wash at home, thinking that bubbles can continue to be used, but this may cause bacteria to grow in the container, resulting in the effect of getting dirtyer the more you wash. In this regard, skin doctor Cai Yiren emphasized that she would never do this. She said that adding water to dilute it for one or two months may make cleaning products more prone to rot and change.

Doctor Cai Yiyan posted a message on his personal face fan group on the 10th, saying that if a whole bottle of new hand wash or dishwashing essence is too heavy, do not add water to the bottle and use it dilutely. Although this will save money and you can change one bottle to two bottles, the content of bacteria in the bottle may also increase, she said. "The water is not completely sterile. After adding it to a bottle of "a large bottle of shower gel (or dishwashing essence), it may increase the content of bacteria or other microorganisms. The preservatives added to the product itself are also diluted due to the dilution of the concentration, resulting in a decrease in the effect." After long-term use, cleaning products are more likely to become corrosive and deteriorated.

But if the cleaning supplies are almost used up, there is only a little left at the bottom of the bottle , when it cannot be used, you can add water to dilute it. Cai Yiyan said, "Because it will be used up in two or three days, you can add water to the bottle to dilute it so that the remaining products at the bottom of the bottle can be used thoroughly. If you are a little "doing (spare work)", you can also use the boiled water to cool down and dilute it, but you still use it as soon as possible." She emphasized that adding water to dilute it, it is best to use it within 3 days, and reminded "Please "please "buy as much as you want, use, buy, and buy, and don't stock up cheaply."
