"The Lotus effect refers to the very high water repellency (superhydrophobicity) exhibited by the leaves of the lotus flower (Nelumbo). Dirt particles are picked up by water droplets due to a complex micro- and nanoscopic architecture of the surface which enables minimization of adhesion. The self-cleaning property of superhydrophobic micro-nanostructured surfaces was discovered in the 1970s and has been applied since the 1990s in biomimetic technical products."

So, if they put this stuff (or something similar) on the walls in public bathrooms, whould it stop the ink from sticking to the walls from all the graffiti?

As well as walls and other places Graffiti Artists like to paint...
