Thank you Kimram :) Which "mood" glass did you choose? Yes, I clean all three materials with the 50/50 solution. Remember, I don't have a shower as mentioned in by the OP. Yes the grout lines are sealed as well as the glass and tumbled travertine. I didn't want to darken the travertine so we used a water based sealer, not an enhancer. Same for the granite countertop. Sealing glass tiles before grouting is important because the fine lines and "crazing" in some glasses WILL be stained by the grout. I don't believe you can seal polished travertine. The sealer can't penetrate. My bathroom floor is 18" porcelain. I use a steam mop on all the tile in my house, including the travertine in the entry. I use a microfiber cloth and the water/alcohol to wipe down the travertine and glass on the walls, on the granite, wipe down appliances, windows...it's become my go to cleaner. Use a spray on granite polisher ever once in awhile. Good luck :) Can't wait to see your beautiful finished bathroom. Monica

I have a pretty good steam cleaner. Just my opinion, but if you couldn't get the tile and grout clean by scrubbing, I doubt that a steam cleaner is going to do it. If I were going to clean this, I would use a product that the guys on the John Bridge Tile Forums recommend, called Stone Tech Restore. I used it when I needed to deep clean a shower stall. This is an acid, and you need to be careful with it - rubber gloves, be careful not to splatter it, etc. But, man, this stuff really cleaned the tiles. Here is a link that might be useful: Stone Tech Restore

Grout hasn’t changed much, and neither has grout care. There are three categories of grout: cementitious, epoxy, and furan. Most of us have cementitious grout (with or without latex). For that, clean tiles and grout with dilute detergent and water. Remember to seal your grout (once it’s dry) annually. Epoxy grout does not have to be sealed, but it can stain; if I’d does, you can brighten it with a dilute bleach or dilute vinegar. Furan is usually black and used in floors in industrial applications.

In addition to regular vacuuming and spot cleaning as needed, for the last almost ten years I've gone over the whole thing with bucket and towel about twice a year. On my hands and knees, I use a diluted solution of Mr. Clean or Soilex. I clean our 16-inch porcelain tiles individually. Although the grout is sealed, I avoid getting dirty water on the grout lines. Rinse with a plain water-wet towel and dry. Gardening type knee pads are very helpful! We have porcelain tiles in entry, family room, kitchen, and two bathrooms. Not all tile is wet cleaned at one time. LOL
