Cleaning Fiberglass Tubs and Showers

I just moved into an apartment with a retro green tub and shower surround. I'm not sure when the last time it was actually clean but it was gross. I mean soap scum and dark grey gunk. Yuck. It was the only big negative of the apt. So today I was reading the suggestions for cleaning and decided to give the oven cleaner and majic eraser a try. OMG!!! It worked great and I didn't even have to scrub it til my arm fell off. Amazing. I'm super happy. I don't mind the "retro" green as long as it is clean....

I have tried just about everything listed here and I will admit the oven cleaner really does work, but something that works astonishing well is a product called EdFred shower stall and tile cleaner. My husband found it at Orchard Supply Hardware store. I thought for sure we would have to replace our entire shower stall but this stuff made it brand new! Also their toilet bowl cleaner also works amazing too.
