as little as possible- and make sure the marble is sealed- it's afairly porous stone, for all its polish, and will soak things up. never ever anything with acids in it- which leaves out even things like windex with vinegar. mostly- there's little that water and a clean rag won't take off.

We have marble border stripes on the tub surround in our MB, and split face travertine border tile on the tub surround in our hall bathroom. Been using 7th Generation Disinfecting Bathroom Cleaner (spray). I spray it on, let sit a few min., and then wipe dry with a microfiber cloth (no rinsing necessary). I usually spray some on the microfiber cloth before wiping in order to help spread it around on the tile and grout lines. We also spray Mrs. Meyer's Shower Cleaner (the daily spray) after showering. I called both companies to make sure those products were natural stone-safe. Some others from both lines are not. I use Marbalex (from SCI) mixed with water for mopping all of our floor tile--travertine and porcelain. It's a no-rinse stone-safe floor cleaner. I don't know if it disinfects, but we are fine with just using soapy water to clean our floors.

Thanks Bill - The link did not work, but I founds something from Miracle sealants - http://store.miraclesealants.com/product_p/miracln.htm Rookie & gam51 - I will check out those two as well. So what did those use before there were all these specialized cleaners? Is there any "homespun" natural choice? I feel like I have a cleaning wardrobe (something different for every surface and wall) these days and long for some simple cleaner to do everything (or most everything.) Is it bad news to use typical all purpose cleaners (sprays like fantastic) and than wipe with water, or use liquid dish soap, or is there some eco stuff that is good? thanks

Getting ready to do an inservice for a client and her cleaning staff after an expensive remodel. Here's what we recommend. Most important tools for the shower regardless of material used: Squeegee and microfiber towel (used after each use, with ventilation fan always); MB-5 for regular wipe downs on all surfaces. Great for marble and granite and can be used on mirrors and glass doors as well. MB-3 periodically if you get build up of soap residue in shower. Damp mop the marble floors and the MB-5 can be used for this as well (minimal water and would not regularly steam clean marble floor as it will break down sealer over time. Do NOT over-clean marble); this non-acidic toilet bowl cleaner is great. Our clients love it. Won't harm the floor around the toilet, won't harm toilet surface, smells fresh and is effective cleaner. Can purchase all from MB Stone Care online. Congrats on your new space.
