I *highly* recommend using a squeegee on any glass in your shower. Sounds so stupid but it keeps the glass so clean and great looking. It might take 20 seconds after the shower to squeegee the walls, and then voila, it looks great. No scum, no streaks. Beautiful… See?
By the way – can you see my cool “shave shelf?” I prop my leg on there, the shaving gel and razor are right there, and bang, the leg practically shaves itself..
