I've tried soft scrub with works but is alot of work scrubbing
I've used bleach and just filled the tub with cold water and let the jets run; haven't noticed weather this helps or not
I've used comet witch I don't use anymore on anything because it leaves a residue
My tub isn't super filthy. Just looking for something that if I stay on top of things, it won't be such a workout just to clean my tub.
