. Don’t drink water with these water cups
1. Use colorful cups. Be careful of heavy metal poisoning. We should pay attention to prevent this. Colorful cups are very attractive, but it’s best not to use them. Because there are great hidden dangers in those bright pigments, especially the inner wall is coated with glaze. When the cup is filled with boiled water or drinks with high acid and alkali, the toxic heavy metal elements such as lead in these pigments are easy to dissolve in the liquid. People drink liquids with chemicals, which will do harm to the human body.
2. Don’t drink coffee in a metal cup. Coffee still needs ceramic cups. Metal cups, such as stainless steel, are more expensive than ceramic cups. The metal elements contained in the composition of enamel cup are usually stable, but they may dissolve in acidic environment, so it is not safe to drink acidic drinks such as coffee and orange juice.
3 Disposable paper cups or hidden potential carcinogens. Be sure to use as little as possible. Disposable paper cups only look hygienic and convenient. In fact, the product qualification rate can not be judged. Whether they are clean and hygienic can not be recognized by the naked eye. From the perspective of environmental protection, disposable paper cups should be used as little as possible. Some paper cup manufacturers add a large amount of fluorescent whitening agent to make the cup look whiter. It is this fluorescent substance that can make cells mutate and become a potential carcinogen once it enters the human body; Secondly, those unqualified paper cups are generally very soft and easy to deform after pouring water. Some paper cups have poor sealing and easy water seepage at the bottom, which is easy to scald hands with hot water; What’s more, when you gently touch the inside of the paper cup with your hand, you can feel the fine powder on it, and the touch of your fingers will turn white. This is a typical inferior paper cup.
4. Plastic cups are easy to hide dirt. Pay attention to these countermeasures and prevention, and do a good job of improvement can reduce the harm. Plastic cups should also be unpopular. Because plasticizers are often added to plastics, which contain some toxic chemicals. When hot water or boiled water is filled in plastic cups, toxic chemicals are easy to dilute into the water, and there are many pores in the internal microstructure of plastics, which hide dirt. If they are not cleaned, bacteria will easily breed. Therefore, when purchasing plastic cups, we must choose water cups made of edible grade plastics that meet national standards.
What kind of cup is good for drinking water?
1, ceramic cup. This is a good-looking and easy-to-use type. Pay attention to make a good choice. The water is easy to be broken and beautiful, but it is easy to leave stains. Many office white-collar workers like coffee, but the coffee cup needs to be special. The glaze on the ceramic surface can’t react with coffee, so choose a special coffee cup. If it’s only for drinking water, it doesn’t matter. Both mugs and insulated mugs can. Be careful not to choose those with patterns on the inner wall. The pattern glaze has a certain impact on the body.
2. Glass water cup. These glass water cups are good. I now use glass water cups. Usually, the raw material is high borosilicate glass, which is fired at a high temperature of more than 600 degrees. When choosing a glass water cup, you should choose a glass with smooth surface, no impurities, no bubbles, no peculiar smell, and no inclination of the bottle body. Glass does not contain chemicals, so drinking water with glass is the safest.
3. Purple sand water cup. This cup is good for making tea. This kind of water cup is generally used by more people to make tea. Purple sand has excellent air permeability. It is not easy to taste tea and tea is not easy to deteriorate. A good purple sand cup can also show one’s taste and identity.
4, stainless steel water cup. There are many kinds of choices. There are many brands that can choose this material, and they are all big brands. Stainless steel cup is firm, not fragile, durable, and beautiful. It is used more as a thermos cup, which is not harmful to the body. But it can’t be used to hold traditional Chinese medicine. It’s harmful to your body.
Simple cleaning method of water cup
salt. Whether it’s table salt or coarse salt, it can help us remove the tea stains on the cup. Method: after touching it with your fingers, brush it back and forth over the tea stain. It only takes two or three minutes, you will find that the tea stain magically disappears, and it is not easy to hurt the cup body.
toothpaste. First rinse the cup with water (without leaving water), then rub it on the cup wall with toothpaste, and then rinse it with clean water.
orange peel. Sometimes when you encounter old dirt and can’t brush it clean, you might as well look for leftover lemons in the kitchen or peel to be discarded after eating oranges. For cleaning the coffee cup, use lemon slices or a little vinegar to wipe the edge of the cup; If it’s a coffee pot, we can slice the lemon, wrap it in a cloth, put it on the top of the coffee pot, and fill it with water. Cook the lemon in the way of coffee and let it drip into the pot below. When yellow water drops out of the coffee pot, this is evidence that citric acid can remove coffee stains. Generally speaking, you can clean the coffee pot about twice.
peel + salt. Using peel to replace vegetable and melon cloth: dip salt and then brush tea stains, which can also achieve unexpected good results. If there is no peel, a little vinegar will have the same effect.
