Ducky

Former hulls were grey. New Ducky hulls are delivered just in white. Certainly, it looks nice. But you see any polution on the surface. Most evil, any ugly grey traces of the alloy beams stay forever on the white hulls and it seems nearly impossible to me to get rid of them.

So how to clean the white hull surface best?

You can clear the hulls by means of household detergents. At strong pollution you can try solvent or white spirit.
