There are many kinds of disinfectants with different functions. Due to the campaign against COVID-19, people attach great importance to daily protection and disinfection. Today let's look at the most common household disinfectant: alcohol. Household alcohol refers to 75% medical alcohol. Because the virus has a protein envelope and alcohol can denature the protein, the virus can be killed by alcohol.
消毒剂种类繁多，功能各异。由于对抗新冠肺炎，人们非常重视日常防护和消毒。今天让我们来看看最常见的家用消毒剂：酒精。家用酒精是指75%的医用酒精。因为病毒有一个蛋白膜而酒精能使蛋白质变性，所以病毒可以被酒精杀死。
When using alcohol for disinfection, be sure to keep away from the fire. When alcohol disinfection is really needed at home, it is better to limit it to no more than 500ml, for a large amount of alcohol is like a hidden bomb. The containers for alcohol temporary storage and use must be reliably sealed and cannot be placed open. Keep away from fire and heat when storing, and the temperature should not exceed 30 ℃. Avoid direct sunlight.
使用酒精消毒时，一定要远离火源。当家中确实需要酒精消毒时，最好限制其不超过500ml，因为大量囤积的酒精就如同隐形的炸弹。酒精暂放、使用的容器必须有可靠的密封，不能敞口放置。存放时远离火种、热源，温度不宜超过30℃。避免阳光直射。
In general, our houses only need to be kept clean instead of being disinfected. But it is necessary to carry out disinfection when there are patients in the house, especially the patients with infectious diseases, or visitors from outside. When wiping alcohol, ventilation must be carried out in time to avoid adverse effects on the body. We should disinfect according to the right way to avoid mistakes.
一般来说，我们的房子只需要保持清洁而不需要消毒。但有病人在家，特别是传染病病人或外来访客时，必须进行消毒。酒精擦拭消毒时，一定要及时进行通气，以免对身体产生不良影响，要按照正确的方式消毒，避免误区。
The following are some other tips for home disinfection. For general families, it is advised that physical disinfection methods should be selected firstly when choosing the methods, such as heating and exposure to the sun. To disinfect tableware, we can use disinfection cabinet. Clothes and bedding can be disinfected by being exposed to the sun. Besides, the house should be well ventilated. When washing hands, if there was no contact with the patients before, use ordinary soap and running water.
以下是一些家庭消毒的其他建议。对于一般家庭，建议在选择加热、暴晒等方法时，应首先选择物理消毒方法。为了消毒餐具，我们可以使用消毒柜。衣服和床上用品可以在阳光下消毒。另外，房子应该通风良好。洗手时，如果以前没有接触过病人，可用普通肥皂和自来水。
When disinfecting frequently contacted objects, such as door handles, stair handrails, foot mats, faucets, etc., the key parts should be disinfected instead of spraying disinfectants on a large area. Don't leave out the disinfection of key items. Take dishcloth as an example, because it is frequently used, often in a wet state and mainly contact with food and other organic matters, so it is very conducive to the growth of bacteria. And the dishcloth should often be disinfected by means of sun exposure, boiling and other methods. In addition, pets are our good friends, so we can't forget to disinfect their nests.
对经常接触的物品，如门把手、楼梯扶手、脚垫、水龙头等进行消毒时，应对关键部位进行消毒，不要大面积喷洒消毒剂。不要遗漏了关键物品的消毒。以抹布为例，因为它使用频繁，经常处于潮湿状态，主要与食物和其他有机物接触，所以非常有利于细菌的生长。而抹布要经常用暴晒、煮沸等方法消毒。此外，宠物是我们的好朋友，因此我们不能忘记给它们的小窝消毒。
