How to maintain motorcycle helmets?

The surface of the helmet is often stained with dust and oil, so wiping the surface is a common job. In case of stains on the helmet, first use a damp cloth to clean the stains, and then rub the car with water wax or glazing wax to make the helmet clean and shiny. A special brightener for helmets can also be used, and the effect is better.
Maintenance of the inside of the helmet.

When the helmet is used for a period of time, the inside of the helmet is sweaty and not well ventilated, oil will accumulate, and an odor will be generated. In this case, it should be cleaned. The cleaning agent used should be neutral. In order to avoid the peculiar smell of the cleaning agent, the usage amount should be controlled. When scrubbing the inside of the helmet, do not use excessive force. Otherwise, the cushioning material inside will be deformed or damaged. After cleaning it, wipe off the moisture with a towel or paper towel, and place it in a ventilated place to air dry. Do not use a hair dryer, etc.
Maintenance of helmet goggles
When cleaning the goggles, since the goggles are transparent parts, be careful when cleaning them. Add a neutral detergent to the water, wipe the inner and outer sides with a soft cotton cloth, rinse with water, and let it dry naturally. Rubbing water wax or antistatic agent on the outer surface can reduce the adhesion of dust and oil. The inner side of the goggles is coated with anti-fogging agent to reduce the fog on the mirror surface when the weather is cool and when driving at night.
