- Let your helmet “breath” for a day after use, to let it dry out.
- Clean the inside with soap and water to remove perspiration, acids, and dirt.
- When not using your helmet, place a non-scented anti-static clothes dryer sheet inside to help absorb odours.
Once a helmet has been involved in an accident, it should be retired. It’s done its job. Even if the helmet only has a few minor scratches on the outside, there are probably cracks inside the shell and a partially crushed foam liner under the padding. So, even if it doesn’t look damaged, it should be retired.
A common recommendation is to replace a helmet every two years if worn regularly.
