b. Cleaning and Inspection
(1) Clean helmet liner with NID solution. Rinse thoroughly with fresh water. Remove foam pads from
pockets in the nylon liner and dry separately to prevent bacterial growth. Squeeze foam, do not
wring. Reinstall when liner and pads are dry.
(2) Inspect helmet liner for fabric damage, loose stitching, or other signs of wear. If fabric is damaged,
the liner must be replaced.
Place the helmet liner in the helmet shell and snap into place.
