How do I deep clean an old fiberglass shower and glass door?


I have a poorly ventilated, nearly 30 - year old shower to clean. Black slimy stuff in the corners, discolored silicone caulk, and a thick, miserable coating of scale in all surfaces, including the glass shower door. I have tried everything, I am ready to try dynamite! Help!

    Use The Works original toilet bowl cleaner in the white bottle with blue letters. I get mine at the Dollar Tree for $1. I clean repossessed houses and this always works better than anything else. It will even remove rust stains.

    Oven cleaner works well just open up the doors and windows in adjoining rooms get a good stiff toilet bowl brush to help scrubbing/reaching up & in corners.Not kidding

      probably should just remove the caulk & clean under it to kill mold then recaulk after it dries well or mold will just regrow there, pretty easy just scrape it off with putty knife or single edge razor scraper held at a slant so you don't gouge fiberglass. I use to clean college dorms and apartments it was challenging but there are easy ways to get the job done & yes to the big box fan blowing/pulling air out of closest window, wear a mask/bandana something over mouth nose while you are scrubbing not so much for cleaner but the mold is actually worse.
