I tried every suggestion in this post and nothing worked for me. I live in New Hampshire and it makes sense stains will be different depending on where you live. Finally, I found the solution ...a pumice stone. There are several brands available online. I found this one in my local grocery and hardware store, and it's pretty inexpensive. Just use with water ..it didn't take a lot of muscle....just a little patience but it worked beautifully. I had gone so far as to get a quote for replacement shower doors and stumbled on this product just before I was ready to place the order. So glad I tried it because new doors were more than $800. Just wanted to share in case it helps someone else!

I found something entirely by accident that works better than anything else I've ever tried. GoJo (or possibly any other type of pumice type of hand cleaner) I discovered it when I was using it in the shower to clean off from helping my husband work on our car I was a mess so I just took it in the shower with me and when I went to squeeze some in my hand it squirted into the shower door, I wiped it off using a circular motion and didn't think anything else about it until later that night I noticed that fist sized circle was spot free. I had the opportunity to try it out on a really tuff situation about a year later when our renter moved out. I dont think he cleaned the shower doors at all during the four years he lived there. I went over it twice but when I was done, they looked brand new

Hi there, This is my first time posting in the bathroom forum (been hanging out in the appliance section), so I'm glad people have the same concerns I do about cleaning the shower! Apologies in advance if this is a bit tangental, but I've been looking at various shower surfaces for our new bathroom remodels. I like the look of tile/stone but absolutely abhor the idea of dealing with the grout and caulking -- it just seems like an inevitable problem. Those acrylic inserts appear to resolve this issue, but they're just so cheap feeling I don't think I can buy into it. Having recently visited a home show, I think I found a really interesting compromise called stonecraft (not sure if that's just the company brand name or the actual product name -- linked below). It's a plastic/cement mixture that they paint in two layers. The first layer goes on solid. Then they 'tape' the tile pattern you want, then apply the second coat (different colour). When the tape's removed, the first layer appears as the grout lines. I first looked at this for my patio deck, but the more I read into it, the more I liked it for other parts of the house -- including the shower (they even suggest it). My contractor worked on another house that used this outside and it really feels like a stone material. As it's painted on, it should be seamless (walls, floor, ceiling)and, therefore, a breeze to clean! Kind of hoping someone's used this and can share their experience, because it seems like a silver bullet. As for the doors itself, I'm wondering if anyone knows how long a shower stall would need to be to go 'doorless' without getting significant splashing out of water.

Where my glass door hinges meet the marble threshold (to the shower) we have brown marks. We have hard water but have a water softener. This doesn't seem to be happening inside the shower, but rather around the outside of the shower where the polished nickel hinges holding up the glass enclose (and door) meet the marble threshold. Any ideas how to clean this off? Obviously with marble we are more limited in what we can use (no vinegar, for example). Please help - it looks awful!
