Choose The Right Leather Cleaner.

The sweater in winter is washed and washed shorter and narrower. This is the reason.

Therefore, when cleaning the dermis with non professional cleaning agents, the alkaline detergent permeated from the dermal pores will corrode the dermis, destroy the internal structure of the dermis, and shorten the service life of the dermis. Therefore, it is necessary to use professional cleaning agents to clean the leather products.

How to identify

1. Test with acid base PH test paper.

PH pH =1~14, neutral =7, acid =1~7, alkaline =7~14, the smaller pH value, the more acidic, the greater the pH value, the more alkaline.

Although the pH value is correct, the neutral value is =7, but in fact, the neutral range can be extended to PH=6.5~7.5.

Put the pH test paper into the leather cleaner to be removed. After a second, remove the pH value according to the reaction color.

The more red, the more acidic, the more blue and black, the more alkaline.

Humans or animals are slightly biased toward esters, namely human or animal.

PH value greater than 7.5 or less than 4, not only hurt the leather, but also hurt the hands.

The qualified leather cleaner has pH pH of =5~7.5.

Acid-base PH test paper is usually sold in teaching and chemical stores.

Two, smell, see volatile

If the smell of leather cleaner is strong, it shows strong volatility, generally contains solvents, air pollution, will enter the body with breathing, is not conducive to human health, harmful to the human body.

Aroma is usually "golden house and charming". It is a way to cover the stink with incense.

Most chemical products smell bad, so they should be disguised with fragrance.

Of course, the spray type leather cleaner is very convenient to use, but users will also passively absorb it, which is not conducive to human health.

Three, look at water or oil.

It can be dissolved in water and has no toxicity or toxicity. It is also environmentally friendly.

Emulsive, generally also belong to water, if alkalinity is too strong, will hurt the skin.

Oily leather cleaners, which contain solvents, are generally more toxic than water and are not environmentally friendly.

But the newly invented products, such as leather imitation oil leather cleaner, are not solvent based, and are not toxic.

Four, leather cleaner should not contain abrasives.

If leather cleaner is used as a friction agent, its cleaning principle is a physical method of grinding and removing dirt. It is like sweeping the floor. If you do not pay attention to it or the technology is not good, it will easily wear the surface of the leather.

But if the dirt is too serious, too special, so that there is no way to remove it. As long as the method is appropriate, that is, only grinding away dirt, the use of friction solution is better than using alkaline corrosion of the internal structure of the leather.

Five, look at the cleaning effect.

Spray the leather cleanser onto the surface of the dermis. If it is clean, it must be very clean. This is the result of chemical reaction. It has a strong corrosive power. Cleaning leather with such leather cleaner will be very clean, but the price is to hurt the real skin. Moreover, when the detergent is used more than three times in the same place, the dermis surface will be abnormal.

Besides, cleaning the pores from the pores into the dermis will destroy the internal structure of the dermis, shorten the service life of the dermis, and also damage the human skin. PH value of its pH value is not likely to be =5~7.5.

Good leather cleaner, its cleaning power is generally not strong, cleaning speed is relatively slow, but it can also thoroughly clean the dermal dirt.

Six. Practical inspection: see

Practice is the sole criterion for testing truth. When leather and leather cleaners are touched, they will be bright or dry, bright and dry, and the leather will be clean. It must be a good product. Otherwise, it will not be a good product.

For dermis, this is the most important test standard.

Seven. It can be degraded and has no pollution to the environment. It meets the requirements of environmental protection.

To sum up, good leather cleaners generally meet the following requirements: first, pH value =5~7.5; two, no smell, no volatilization; three, water; four, no abrasives; five, moderate cleaning power; six, after contact with the genuine leather, immediately bright or dry, bright, real leather will not be hard, and has the cleaning power to clean the skin dirt, will not pollute the environment, meet the requirements of environmental protection.

Among them, one or two, three and so on three points will affect people's health, therefore, we must attach great importance to health is more important than anything else; one, four or five, six and four points can judge whether leather cleaners are harmful to the dermis; five or six points are practical tests; seventh points can judge the impact on the human environment.

Due to the limitation of science and technology, the leather cleaners on the market are hard to satisfy the above conditions at the same time, especially the first and 62 conditions. Most of the leather detergent can not be satisfied.

However, the newly invented leather imitation oil leather cleaner, mepid leather cleaner or MeJA leather cleaner, can meet the above requirements. It is based on the principle of meat cleaning (meat cleaning, no cleaning agent, putting meat in water, cleaning with meat, that is, no need for any cleaning agent), no skin damage ingredients, not only cleaning the dermis, but also having the functions of beauty, maintenance, mildew proof, waterproof, anti fouling and so on.

Finally, leather cleaning agents should be selected according to their leather products. Different leather should be made of leather cleaner, such as frosted leather, suede leather and other special leather. Ordinary leather cleaner should not be used.
