What is the way to easily remove the stain

Wind oil essence. Scotch tape.

Baking soda. 1. Skillful use of wind oil essence.

A lot of people like to use alcohol to wipe their screens, but that's not true. Due to the composition of alcohol, it is possible to dissolve the screen coating or coating layer, and over time, the screen will become more and more flowery until it is not clear to see, so it is not recommended to use alcohol frequently to clean the mobile phone screen. Actually, we can use wind oil essence.

If you look closely, you will find that many professional film masters will wipe the screen with wind oil essence before applying the film, not only because the wind oil essence has a good cleaning effect, but also because it will not damage the screen. Just put two drops on the screen and wipe it with a soft rag.

2. Use scotch tape.

One of the biggest benefits of using scotch tape to clean the screen is that it can clean the phone's fine dust, especially the dirt that gets stuck in the gap between the screen and the frame around the phone. If your phone is greasy and dusty, you might as well try this method, which is simple and practical. However, it should be noted that it is best to use adhesive tape, otherwise it is easy to cause the mobile phone screen to become more and more sticky, or even damage the mobile phone screen.

3. Use baking soda wisely.

All you need to do is add some baking soda to the water and wipe the screen with a microfiber cloth, and soon the phone will be shiny and beautiful, just like new. This is because sparkling water is weakly alkaline, which can neutralize the grease on the phone screen, thus achieving the effect of cleaning and decontamination, and at the same time, sparkling water does not contain anything that corrodes the screen. This method is simple and reliable.

The decontamination effect of edible alkali is better, we usually have stains that can not be removed, the edible alkali is soaked in hot water, take a cloth and wipe it if you want to wipe it**, it is particularly easy to use, we have used it for many years, **affordable, cheap, very easy to use, the main edible alkali does not have any additives, will not harm the body, non-toxic and non-additive, very easy to use.

No matter how dirty or difficult the slippers are, it is great to use a simple method to easily decontaminate and clean.

1.Organic solvent method.

The organic solvent method uses the principle that oily dirt is soluble in organic solvents for cleaning. Commonly used solvents are toluene and xylene.

Gasoline, alcohol, tetrachloroethane.

and turpentine, etc. Organic solvents have a strong solubility in grease and grease, and only a small amount of solvent is needed to remove a large amount of grease and dirt. The cleaning operation is convenient, if the degreaser is selected correctly, it can quickly remove the oily dirt, and the general mixed solvent has a better washing effect than a single solvent, and the cleaning range is also wider.

But most organic solvents are volatile, flammable, and even **. There are certain dangers in the process of production, transportation and use; Most organic solvents have certain toxicity, and long-term exposure to the human body will damage some functions to a certain extent, especially the halogenated hydrocarbons that are more toxic.

Solvents such as methanol and ether. Moreover, it is not suitable for large-scale use in industrial production, because of its high cleaning cost.

2.Alkaline lotion method.

Alkaline lotion method is a chemical cleaning method based on alkaline substances, because of the low cleaning cost, so it was widely used in the early days, alkaline washing liquid method has a significant degreasing effect, low cleaning cost, and was used to clean oil stains in a variety of industries in the past. However, alkaline lotion has strong corrosiveness to washing articles and operators, alkaline lotion has no effect on non-saponified grease, can not remove mineral grease, and has certain limitations; Moreover, the objects that have been cleaned by alkaline lotion need a large amount of water to be cleaned, which is more water-consuming, and is generally used to wash ferrous metals without obvious corrosive effect within a certain concentration range.

and certain non-metallic materials.

3.Water-based surfactants.

Cleaning method. The water-based surfactant cleaning method is a method of cleaning oil stains using an aqueous solution with surfactants and a variety of detergent additives. The aqueous solution of the surfactant has wetting, emulsification.

Dispersion, infiltration, peeling, solubilization and other functions can make a variety of oily dirt emulsified and peeled in the cleaning solution to achieve the purpose of complete dissolution and removal. The addition of a variety of additives can significantly enhance the washing capacity and reduce the washing cost. Most of the oil scales in industrial production are mixed oil stains, organic solvents and general alkaline cleaning agents have poor cleaning effect on this kind of mixed dirt, mineral oil scales that cannot play a saponification role in lye, and the cleaning effect of water-based surfactant cleaning agents is relatively good.

The water-based surfactant cleaning method is a very simple and safe cleaning method among the current chemical cleaning methods, and does not produce violent chemical reactions.

It is usually carried out in cold or warm water, which is not easy to volatilize, will not corrode the workpiece and **, has low cleaning cost, is convenient for transportation, easy to store, and is very suitable for use in industrial cleaning.
