I only use water on my crash helmet and visor. I just would not feel comfortable using any products. I cover the lid and visor with wet kitchen roll and leave it to soak, then clean the whole lot with a v2 sponge (£2 well spent) and dry with a clean non abrasive cloth. Just had a load of Wurth products delivered for suscribing to Bike magazine. Just about to find out if they are any good. |
