First of all, the life of dermis and the hardness of skin have a great relationship with the oil stored in it. How to understand it? Just like whether a down jacket keeps warm has something to do with the duck down inside. If the duck down is not fluffy, the down jacket will not be so warm to wear. After understanding clearly, we need to pay attention to what will destroy the oil inside the dermis.

Exposure will accelerate the disappearance of oil in leather.

1 Long-term exposure of cars in the sun will accelerate the disappearance of oil and water in leather. SAIC Volkswagen made an exposure test with the leather of automobile interior. The results show that after 13 months of exposure, the leather seats of some models have hardened, and the BLC softness value has changed from 3.5mm to 2.5 mm after exposure. To exaggerate, the sofa is a bit like a board. Therefore, when the temperature is high in summer, it is best to park your car in the shade if conditions permit, and at least get a sunshade if conditions do not permit.

Mould can destroy the grease inside leather.

The second point is that the seat surface is not cleaned for a long time, which breeds mold and also causes the oil in leather to be destroyed. According to some data, Huang Xu of Chongqing Changan Automobile Co., Ltd. and others published a paper "Design of Anti-aging Verification Test for Automobile Interior and Exterior Accessories". It is mentioned that mold will decompose and destroy materials by eating away at plasticizers and grease compounds in polymer materials.

Stains will get into the leather and get old.

Although this situation is rare, it is no problem to pay attention. And if the seat is not clean for a long time, it is easy to get old even if it is not aging, especially in light color. It's very simple. The leather surface has texture and pores, which are all from animals. Mixed pollutants such as gravel, human sebum and sweat will not only adhere to the surface, but also enter the bottom of pores and texture.

To tell the truth, some dirty things can't be washed off if you simply wipe the towel a few times. If you wash it for a long time, it will stick to it completely and look old.

Avoid using cleaning agents with strong degreasing ability such as acid and alkali.

Third, although some friends regularly clean leather seats, the materials used are not selected, which in turn may destroy the oil inside the leather and lead to aging of the leather.

As long as it is a cleaning agent, it will be acidic, neutral and alkaline. Some interior cleaning agents, in order to improve the decontamination ability, will be made alkaline immediately.

The stain was removed, but the grease in the leather was also washed away. It doesn't matter once or twice, and you will praise it when the effect is good. "How can it be so easy to look old when you use it too much?" I hurt my skin. Neutral interior cleaner with bactericidal effect is better. If you want to clean and maintain the leather seat better, you must first choose a selective interior cleaner, so that it is not easy to damage the grease inside the leather.

Some friends are worried that "the decontamination effect of neutral detergent is not so good." No, neutral interior cleaner will add surfactant and emulsifier to dissolve stains, and the formula is milder, which means more pertinence, not necessarily stronger alkaline cleaning ability.
