A simple and super effective way to clean shower glass! And it works!
Shower glass is notorious for discoloration and calcium build-up that won't shift no matter what you do. My shower glass was pretty well covered and the usual shower cleaners didn't work. I found a simple answer to the problem. Believe it or not, super fine wire wool does the trick. Wire wool comes in various grades, the finest is '0000' and that's what I used, I rubbed down a small area at first and the result was amazing, it lifted the calcium marks clean off in seconds. Best of all it doesn't scratch. Most good hardware stores stock fine wire wool, and there are quite a few brands available, I happen to use one called SIFA which worked fine but I don't think the brand name will make a difference, it's the grade '0000' that matters. BTW it also works on balcony and swimming pool glass.
