Well, I hope this is in the right spot. This is a little confusing.
Anyway, I'm a professional house manager and one of my clients had her marble shower damaged by a housekeeper who installed an automatic 'scrubbing bubbles' machine which sprayed a chemical daily on her marble - don't get me started. So, now it's streaked and looks terrible. You wash it but it never looks clean. It always looks like it has dripping 'hard water stains', but it's really the damage from the chemical.
I read both these pages (as linked below) and now I'm confused if we just need to do a caustic soda and water treatment (vertical walls...) or if we need to do that as well as re-polish it as outlined in the 2nd article link - which incidentally has tons of broken links to the products. I have found/fixed them to show my client but the article needs updating. Great article - the fixed links would be awesome!
So, here's the first article on the caustic soda and water (but I need to do it on a vertical surface)
http://www.granitehelp.info/index.php/topic,295.0.htmland here's the article I read that has her exact problem, but includes buying a variable angle grinder as well as some Dia-glo and polishing pads - and these links are all broken so while I can figure out the polish and grinder, I'm really unclear what back pads to get since all I see have different grit strengths and if you put a felt pad on it, then the grit doesn't matter.
