I found this neat tip for bathtub cleaner on Pinterest. Jen from Life Crafts & Whatever explains that to bust soap scum add 1 part dish soap and 1 part white vinegar to a spray bottle and spray on your bathtub surface. (I used Ajax dish soap instead of Dawn.)
I've been meaning to clean the tub for weeks but I forget soooo easily. I shower without contacts which means the tub below me is a fuzzy blur. The last time I cleaned it with bleach cleanser, the tub didn't look any cleaner and I hate feeling the cleanser residue on the bottom of the shower.
I went wild with the spray bottle and then left the solution on the surface for about an hour. I made sure to open my bathroom window. I was surprised how potent the mixture was and had to open the window and head out of dodge. Looking back, I probably used 2x the amount of solution than I actually needed.
I was pretty skeptical that I'd get the same amazing results. But, after some scrubbing and rinsing, my tub looks better than ever! (I thought about taking a 'before' picture but it was just too embarrassing.) It was so nice to step inside my tub for the first time knowing it was clean AND completely grit free!
