5, soaked in vinegar for 30 minutes, and then washed away with water, the effect is equally good.
Mainly engaged in the research and development of environmental protection energy and products, telling us that triangles represent recycling and numbers represent materials. There are many kinds, 100. This sign is like a small ID card for each container. They are made of different materials and have different uses.

How can a lunch box that clearly says that it can be heated in a microwave oven become soft and melt? The reason is that when cooking oil is heated by microwave oven, the highest oil temperature can reach nearly 200 degrees Celsius. Moreover, the greater the amount of oil, the faster the temperature rises. Therefore, it is best not to use lunch boxes to heat oily leftovers such as boiled fish and braised eggplant in the microwave oven. When heating other dishes, pay attention to open the lid when heating, and the heating time should not be too long, so as to avoid excessive oil temperature and precipitation of harmful substances.
In addition to complicated steps, there are simpler ones:
1. Soak warm water in the washing solution for 30 hours, and rinse it off slightly.
2. Soak in 84 disinfectant 10 minute.
3. Rinse with water.-Okay.
Safety tips:
Knowing the disinfection situation of plastic tableware, shouldn't we breathe a sigh of relief? What I want to say here is, no, the plastic tableware you buy does not have to go through a very strict disinfection process. The house needs to be disinfected again to be practical. In addition to disposable plastic tableware, we also know the different methods of making other plastic tableware that can be used many times.

How to disinfect plastic tableware? Are ceramic products poisonous?
Heavy metals such as lead and cadmium in ceramic tableware exceed the standard mainly because of some decorative materials on the ceramic surface. The main components of ceramic oil are heavy metal salts such as lead and cadmium, among which lead content is the highest. In order to reduce the production cost, some small ceramic enterprises often use cheap decorative materials with high lead and cadmium content and unstable performance, or put too many blanks in the kiln to make it difficult for lead to volatilize, or shorten the baking time or lower the baking temperature at will, which may easily lead to excessive lead content in ceramic tableware. If people eat with such tableware for a long time, lead will accumulate in the human body and cause chronic lead poisoning for a long time.
In order to prevent ceramic tableware from damaging our health, we should learn how to choose good ceramic tableware. According to different decoration methods, ceramic products can be divided into underglaze color, underglaze color and underglaze color, and underglaze color is a poor one, so it is best to choose underglaze color or underglaze color ceramic products. Under-glaze color ceramic products look as if there is a "safety film" on them; The in-glaze color is fired at a high temperature of about 1250 degrees Celsius, and there is no need to use materials containing lead and cadmium, so the in-glaze color and the in-glaze color are relatively safe.
Newly bought ceramic tableware can be soaked in vinegar for a period of time, which can precipitate most of the lead and cadmium, and then washed repeatedly with clear water, which can further remove heavy metals such as lead and cadmium from tableware.
Are plastic products poisonous?
Plastics are difficult to degrade, and the use of plastic products is resisted all over the world for environmental protection. But plastic products do bring great convenience to our lives, so plastic products are still widely used now. It should be noted that some plastic products are toxic, so be careful when using plastic products.
Know how to choose a good plastic wrap: plastic wrap is often used in the family, and plastic wrap is also good or bad, so it depends on the scope of application when choosing plastic wrap. Now there are two kinds of plastic wrap, one is refrigerator plastic wrap and the other is microwave plastic wrap. The latter is superior to the former in heat resistance and non-toxicity. In order to avoid trouble, consumers had better choose the latter, otherwise they will use it separately. It also depends on the raw materials used for plastic wrap. Plastic wrap is generally made of polyethylene and polyvinyl chloride. Polyethylene plastic wrap without plasticizer is much safer than PVC plastic wrap with plasticizer. In addition, it depends on the cold and heat resistance of plastic wrap. If you need to heat for a long time, you should buy plastic wrap with good heat resistance.
Know how to choose a good plastic bag: it is common to use plastic bags, but some plastic bags are harmful to human body, such as plastic bags made of PVC, which are toxic varieties. Although PVC resin is not toxic, when making plastic bags, plasticizer dibutyl phthalate or dioctyl phthalate will be added, and then it will be toxic. It is worth noting that ultra-thin plastic bags are generally made of recycled waste plastics, and most of them have not been disinfected, so their safety can be imagined. Therefore, it is best not to use ultra-thin plastic bags, especially bulk food. Here is a method to identify the quality of plastic bags: non-toxic plastic bags are milky white, translucent or colorless and transparent, elastic, and the surface looks like a layer of wax; The color of the toxic plastic bag is cloudy or light yellow, and it feels a little sticky when touched by hand.
