The principle of detergent removing oil stains

Detergents can be said to be inseparable in our lives. When washing dishes, we often use some cleaning agents to remove some oily substances. The principle of detergents is mainly the principle of emulsification, and it mainly relies on emulsifiers to achieve the effect of removing grease. In daily life, in addition to cleaning, you can also use some tips to achieve a good effect of removing oil stains.

It is based on the emulsification principle. Specifically, it mainly relies on emulsifiers, which are generally amphiphilic molecules (both hydrophilic and lipophilic). The lipophilic end of the emulsifier can wrap up the oil stains on the clothes, and the hydrophilic end is exposed outside. According to the principle of like dissolves like, the "oil stains on clothes" wrapped by emulsifier can be dispersed into water and washed away.

The structure of dishwashing liquid is divided into two parts, shaped like ×———————————→

One end (polar) is a hydrophilic group that easily combines with water.

One end (non-polar) is a lipophilic group that easily combines with oil stains.

When detergent is dissolved in water and used to clean dirt, the lipophilic end will be inserted into the oil and dirt, while the hydrophilic end will be surrounded by a large number of water molecules. (Like an arrow inserted into the body of prey) After rubbing, the dirt is dragged off the utensils and clothes.

We use a similar principle when we wash our hair with shampoo. It’s just that shampooing washes away the oil secreted by the hair.

1. Principle of acetic acid degreasing

I wonder if you have ever tried using ketchup, which is very popular online, to remove grease stains? I think ketchup is so delicious, isn't it a waste to put it into the pot? If it is expired, that's great.

The acetic acid in food can react chemically with oil stains, making it easy to remove the oil stains, so we can completely use other methods instead.

Just mix vinegar, detergent and boiling water, and wipe it with a clean rag. The kitchen wall is also easy to clean!

When cleaning the microwave, put a cup of water in the microwave and heat it on high heat for 2-3 minutes. The steam in the microwave will soften the grease and make it easy to wipe off.

After wiping the faucet with the peeled potato pulp, it will instantly become bright and new, but the corners are not easy to clean. Therefore, you can use a toothbrush to pick up toothpaste, and you can also easily remove water stains, etc.

3. Tips for cleaning range hoods

The range hood is the most oily part of the kitchen and is very troublesome to clean, so we can wrap the box with plastic wrap and tear it off when the time comes! It is very convenient and fast.

For existing grease, you can take a plastic bottle, poke 10 small holes on the lid, then put in an appropriate amount of detergent and fill it with warm water and shake it evenly; start the range hood, use the plastic bottle filled with detergent to spray the cleaning liquid on the area to be cleaned, and continuously pour out the oil bucket filled with grease and dirty water until the water becomes clear.
