I was disgusted with the filthy condition of a shower in the house I moved into, so I used car cut/wax to safely remove the grit and grime. I then applied Gel Gloss, a product used to polish fiberglass boats (and prevent salt and other build-ups). Now water beads up on my shower walls. I just give it a quick wipe with the used bath towel or SCOTT® Towels to absorb the water beads. These two steps took a bit of elbow grease at first, but it has been over a year now, so it was well worth it. The shower is spotless after a quick wipe dry.
