I have noticed since using handmade soap that I get scum build up much quicker now. :roll:
I spritz the shower bottom and walls with vinegar after showering and it makes cleaning much easier and no more frequent than before. Years ago I read to polish the shower/tub doors with car polish. I have been doing that ever since and the water beads just like on a car and runs off leaving no streaks. About 3-4 times a year, I wash really well and re-apply the wax, then buff off.
