Used a long time Electric vehicle helmet What's the cause of the dirt

The outer surface of the lens and helmet is dirty: with the arrival of summer, some flying insects will inevitably hit the lens violently when riding, leaving some marks. Even if you wipe most of the marks with gloves, there will always be some stains from the mosquito's viscera on the windward side of the lens and helmet body. In addition, in rainy days, the helmet lens and helmet body will also become dirty due to rain splash and dust deposition, and the lens will become blurred, affecting vision and riding safety.

The lining of electric vehicle helmet is dirty: after wearing the helmet for a long time, especially without a hood, due to the greasy hair and sweat, the lining surface will form a layer of stains, or even penetrate into the sponge surface. Bacteria grow over time, and the whole helmet will have a peculiar smell, such as the smell of sweat. In addition, if you wear the helmet many times in hot weather and do not use it for a long time, you will find that the lining on both sides of your cheeks is prone to plaque. This is because the keratin of the skin rubs the lining fabric and remains on the lining, leading to bacterial growth.
