The best way to remove the oil film on the windshield and how to remove the oil film on the automobile glass.

Automobile glass oil film can be cleaned with soapy water, hot soapy water, acetic acid and professional cleaning agents, as follows:

1. Wash the windshield with household soapy water to remove the true oil film layer on the glass surface, or wash off ordinary ash layer by layer, which is beneficial to further cleaning.

2, soaking in hot soapy water, if ordinary cleaning is not clean, then it should be soaked in hot water. Because hot water can provide heat energy for molecules, molecules will move more violently after gaining energy, so that van der Waals force is lost and hydrogen bonds are broken. Finally, the physical adsorption layer of this layer is cleaned and removed.

3. If there is residue. It is suggested to add acetic acid to water to wet the glass surface and then clean it. Acetic acid is a weak acid, which can decompose most calcium deposits and finally clean the glass oil film.

4. Use a special cleaner: If it doesn't work, it is recommended to use a professional cleaner. Or scrub with hydrochloric acid solution. Hydrochloric acid is a strong acid, which can dissolve and decompose most organic or inorganic substances, including metal oxides, and has no effect on glass. Because the main component of glass is sodium silicate, it is only soluble in hydrofluoric acid and strong alkali.

Precautions:

1, after a long period of exposure, heavy rain brushing, wind erosion and other reasons, a large number of holes or rough surfaces appear on the windshield surface.

2. Some oil substances, car wax substances and dust all over the sky when walking will easily adhere to the rough surface of the windshield. After a long time, a small number of substances will form chemical bonds with glass, which is more difficult to clean, so such an oil film layer will appear.
