How To Maintain A Mountain Bike Helmet

  • If your helmet has liners or paddings that can be removed, check the instructions on how to clean them. They are usually washable by machine.
  • Rinse it well after cleaning with soap and water.
  • Remove liquid from the straps by blotting using a dry towel.
  • Air dry is the best way to get rid of excess water.
