One very strange phenomenon is that some people now use milk to protect plastic hollow boards , which is really unheard of. Can milk really be used to protect plastic hollow panels ? **
Xiaobian learned that the milk after the expiration really has such effect.
First of all, we know that milk is always after the expiration acid, which has led to an ingredient in milk - increased levels of lactic acid, and lactic acid is a natural detergent, it is very effective to clean the plate.

Secondly, contained in milk protein, fat and other substances, can form a protective film on the hollow plate, it not only makes the plate look like new, but also to protect the sheet metal surfaces from wear or scratching problems are of.
Finally, the grease in the milk rubs on the surface of the hollow plate, and also protects the original color of the hollow plate so that it does not decolorize or discolor.
It seems that the protection of milk for hollow boards is really not to be underestimated. As long as we rub hollow plate, the expired milk into the basin, and add twice as much water for dilution. Milk into water and then wet rag, cloth after wiping can be wrung the hollow plate. Â
It is a waste to dump the milk after it expires. Since it can be used to protect the plastic hollow board , why not do it? Â Â Â
