Let us know if the peroxide gets rid of the shower gunk. I've tried all kinds of cleaners to no avail.
IIRC the regular hydrogen peroxide didn't do much against those discolorations.
One of the niche magic ingredients to look for is TSP. Alongside bleach (consult proper sources for actual ratios) the combination becomes more powerful against mildews.
