Finally! Last night I smeared a combination of hot vinegar (microwaved 2 minutes and an equal amount of blue Dawn. I had used it last year (guest bath only used once a year). I followed the directions, just let it sit and the bottom of the tub looked great. It did not budge the insane soap scum on the side of the tub. The tub was only used during Christmas vacation by our adult daughter who never cleaned. I was in panic mode tonight and saw someone above mention Awesome Cleaner from the Dollar Tree. I put a little water in the tub to wet the vinegar/dawn mixture from last night, swished my scrubber pad in it to wet it. Poured Awesome powder on it and thanked God because it worked! I could not believe it worked and was in panic mode because my daughter is bringing her boyfriend in town with her! Now if I could just get the rest of the house presentable!

marble is quite delicate to deal with. I'm not that knowledgable about these kinds of things but I've read something that just might help. This article will show you what products to use with sample tests on a marble surface. Hope you find it useful. Here is a link that might be useful: Cleanign Solutions (Test on Marble)

Sounds like scale build-up. You can buy scale remover or use vinegar. You could use the same idea of soaking a towel in the scale remover or vinegar and leave it over night. I would use some old rag that you can just throw away and probably cotton would be best if you choose to use that scale remover which is kind of strong. Vinegar will probably not harm a cloth. This may take a few times to get it all. But if it's hard and sharp that would most likely be scale from your water. We have scale in our water and vinegar gets it off. It can also build up on the shower head and cause the water to not come out very good, you can put vinegar in a baggie and put it on the shower head and use some tape to hold it there over night. It will be clean in the morning!

Am I the only one who hasn't had success with the Dawn and vinegar? Our tub has build-up from the previous tenant who was elderly and took baths. The tile was spotless, because of the baths, but the tub bottom is rough. On the other hand, that's good for no slippage! I first saw the dawn and vinegar 6 months ago, and I see no difference in the tub and tiles. I can't get the taps clean, they have water spots. Funny, we have soft water too. The smell is very strong, I keep the door closed and the window open and it lingers in the apartment. Also there's no need to heat the vinegar from what I've read. I heated it once but not since.
