Shift-It Helmet Lining Sanitiser is a special formulation, which lifts grease and dirt from the lining of the helmet without undue moisture. It contains a biocide that not only keeps the interior of your helmet clean, but also effectively eliminates bacteria and unpleasant odours. Shift-It Helmet Lining Sanitiser has been designed to create a foaming effect that actively lifts small particles of dirt out of the lining, reducing interior friction, therefore prolonging the life of your helmet lining.
