Wow . . . . :\
Or an even better idea . . . . kids, rather than using comparatively expensive and dangerous methanol to clean your vehicle (dangerous because it burns clear – you will see your clothes melt and not see the flames burning you! :whhooo

. . . instead of carrying around a bottle of water to reduce the risk of being melted and horribly scarred by an invisiable fire, add some regular, everyday, common household, non-combustible dishwashing detergent to the bottle of water, and spray that on your vehicle to clean it.
