If you were to vote for the three most annoying household chores, dishwashing would definitely be at the top. Some surveys even found that dishwashing is the number one household chore that is "most likely to damage the relationship between husband and wife"! Let’s talk about “washing dishes” today! Hiho ~ Hello everyone, I am Zhiqi! Washing dishes is a painful task for many people. After working all day, they come home and feel tired after eating . When they see a pile of dirty pots and pans in front of them, they feel tired , especially those that are greasy and greasy. The pots that are difficult to clean can't be cleaned no matter how hard they are, and sometimes the more you scrub, the angrier you get! And because of these situations, we are very curious about how to wash the dishes so that they can become clean easily! What is the most scientific way to wash dishes? Are the various dishwashing secrets such as rice water and enzymes really useful? So today let us talk about the "science of dishwashing" and let you learn the magic of making dishes clean! [The principle of washing dishes? 】 To understand how to wash dishes most efficiently, we must first recognize who the enemy is. Generally speaking, the dirt on the dishes can be divided into three categories. The first category is dirt that can be dissolved in water, such as starch. Or seasonings such as salt, sugar, vinegar, etc. These water-soluble dirt will dissolve in the water and be taken away by the water as long as they are washed with water. It is relatively simple and easy to deal with. The second more troublesome thing is that it cannot be dissolved in the water. The dirt in the water is the so-called oily substances such as cooking oil, butter, animal fat, etc. Because oil and water are incompatible, these dirt cannot be directly taken away by the water. At this time, dishwashing detergent should appear. There is a very important ingredient in dishwashing liquid called "surfactant". Surfactant has both "hydrophilic" and "lipophilic" properties. When you wash the dishes, one end will be inserted into the dirty and oily ones. The thing wraps up the dirty things and the other end will dissolve in the water , so that the whole package can be taken away by the water. In addition, there are some organic solvents, alkali and other ingredients in the dishwashing detergent , and they all play similar roles. That is to say, it helps the grease dissolve and be washed away by water . The last third type is the solid matter that causes the most headaches, such as roasted and burnt food, broken bones, dried vegetable residues, etc., which are used in washing dishes. Sometimes these dirty things cannot be completely treated with water and dishwashing liquid. At this time, you have to rely on dishwashing tools. Use friction to brush hard to physically brush the things away. In addition, scrubbing can also increase the speed at which the dirty things dissolve and let the water Use dishwashing detergent to combat these stains more effectively. Now that we know the principles of dishwashing, we can then take a look at the dishwashing myths in the market, which are right and which are wrong! [Is there any knowledge about dishwashing water? 】 From the front, we can find that no matter what kind of dirt we are dealing with, water plays the most important role in the dishwashing process. Then the question becomes, what kind of water is the most efficient to use for dishwashing? The most critical factor here is actually the water temperature, because high water temperature can dissolve water-soluble dirt faster. Therefore, generally speaking, water with a higher temperature will have better washing effect , so most dishwashers on the market currently use 54 to 70 degrees Celsius. If you want to wash with hot water of 80 or 90 degrees, why not just use hot water of 80 or 90 degrees? Doesn’t it mean that the higher the temperature, the more effective it is? This is because water that is too hot may cause the "surfactants" in some dishwashing detergents to fail , and if you wash by hand, your hands are unlikely to be able to handle it if the water temperature is too high , so some experts recommend that when washing with difficult to deal with For dirty things, you can soak the dishes in hot water and then rinse them with cold water. This will make dishwashing easier. Another common discussion is about hard water and soft water dishwashing. Some people worry that it is easier to wash dishes with hard water. If you eat the scale left behind , it will cause kidney disease. But if you use soft water, it is said that it will cause cardiovascular disease. What should you do? According to the existing research, there is no way to directly prove that "the softness and hardness of water can cause diseases." Therefore, if you simply use ordinary tap water to wash dishes, the dose of harmful substances will be very small and will not cause health effects . However, if you use hard water from a dishwasher If it will reduce the life of the machine , it will be necessary to use softening salt or other methods to soften the water. After talking about health , we can talk about the most important question : how to wash dishes most efficiently? A study in Germany found the best way to wash dishes. First prepare two basins, one with hot water and dishwashing detergent to wash the dishes , and the other with cold water to rinse the dishes and then let them air dry. Experiments have proven that this method is not only the most water-saving, but also has the best cleaning effect. It is the most efficient way to wash dishes. If you are interested, you can try it! [What dishwashing liquid is the best? 】 After talking about water, let’s take a look at the second protagonist, dishwashing detergent . In 2016, a survey by National Taiwan University found that more than half of the dishwashing detergents sold on the market had excessive formaldehyde. If eaten by mistake, it may cause irritation to the mouth and nose. It may cause cancer, weaken immunity , and even cause miscarriage and fetal abnormalities in pregnant women . Why are there such dangerous things in dishwashing liquid? According to experts, most dishwashing detergents do not intentionally add formaldehyde to them , but the preservatives used by some brands may release formaldehyde after dissolving. Although this is true , the dose of formaldehyde released in dishwashing detergents is generally small. It will not be eaten directly , so it usually does not cause too obvious harm. If you want to be on the safe side , it is recommended that you read the label and avoid dishwashing detergents with the following ingredients or directly use the so-called "natural dishwashing detergent" here. Dishwashing liquid includes using "enzyme", "rice water" or "soda water" to wash dishes. Can this kind of dishwashing liquid really clean the dishes? In fact, natural dishwashing detergents also work by refining "organic solvents" and "acids" from natural substances, so they still have a certain cleaning power . However, these natural dishwashing detergents lack "surfactants" in their natural ingredients. The cleaning effect will be weaker in comparison , or additional "surfactants" need to be added to it to enhance the cleaning effect. Another thing worth noting is that some people make their own natural dishwashing detergent at home because the environment and formula ratio are relatively different. Instability can sometimes turn dishwashing liquid into a breeding ground for bacteria, which is also harmful to health. But in summary, whether it is artificial or natural dishwashing liquid, the key point is that when washing dishes, you need to rinse the dishwashing liquid thoroughly to avoid eating the residue. In order to achieve this, experts recommend not to use too much dishwashing detergent and flush it with water every time you use it . This way you can eat safely and healthily! [Cleaning tools are super important! 】 Finally came the cleaning tools! When it comes to dishwashing tools, the most commonly discussed dishwasher may be the dishwasher. Some people think it is a marriage savior , but many people are also worried about whether the dishwasher can really clean the dishes? Many studies have found that dishwashers can effectively clean dishes most of the time because of their high-temperature flushing and direct drying characteristics. They can even save more water than traditional hand washing methods . Of course, the disadvantage is that most ordinary If the dishwasher uses a water column to rinse and the scrubbing force is not strong enough, Some stubborn solid substances still cannot be removed , and some studies have found that if the bleach in the dishwasher is not rinsed carefully, it can easily remain on the tableware and cause harm to the human body . Therefore, experts suggest that when using the dishwasher, you can set one more cleaning cycle. Wash it by hand again at the end to ensure that all residues in the dishwasher are rinsed away. However, dishwashers are not very popular in ordinary households. The most popular scrubbing tool is the national artifact "Cai Gua Bu"! The cleaning principle of caiguabu is easy to understand . It is to use the sponge part to foam so that the surfactant can work better . That's right. The sponge is used for foaming , not for washing. The brush part needs to be rough.

However, as the times progress, more and more people are starting to use non-stick pans and high-end pots. The most common problem when using vegetable cloth for tableware is the worry of damaging the dishes and pots . This problem is basically a contradiction.

They sprayed glue and abrasive particles on the intersection of fiber and fiber to make vegetable cloth , which can grind dirt very finely and brush off the dirt without damaging the tableware itself. In addition, the foaming effect of the sponge can let the dishwashing liquid inside The active surfactant completely foams and takes away dirt more efficiently!
