Every time you come back, use cotton cloth dipped in alcohol (industrial alcohol) or white electric oil to wipe the surface of the helmet. Do not use harder cloth to wipe it, as this will scratch the helmet shell!

Remove the stains and dust on the surface of the helmet, and if possible, apply car wax on it to make it more shiny.

Some riders accidentally scratched their helmets on hard objects while riding, which means we need to repair them. The method is simple, which is to squeeze a little bit of our commonly used toothpaste onto the scratch, and then rub it back and forth with a cotton cloth repeatedly. This can make the scratches smaller and larger, while the smaller ones become less obvious.
