Bump. Anyone?

My kitchen floor is now dark grey....:0) I just used platinum grey grout on bathroom floor...time will tell.

We used TEC "Mist" for our MBR grout, and after 2 ½ years it looks like new. It's on both shower and bathroom floor.

In 2008, we used Laticrete Pro Epoxy grout in our master bath. I forget the name of the whitish grey, but as far as I can tell, it hasn't visibly darkened or changed hue, still looks the same. No stains either.

I'm almost positive I used warm gray grout in my powder room. I had white penny round installed and wanted gray grout. I think I've had mine for 1.5- 2 years and the gray grout now has darkened and looks dirty in the high traffic area. Never again will I put light grout on the floor. My laundry and master bath has charcoal grout and looks great.

I don't know which grout brand or color they used, but I have a mid/light gray grout in my guest bath that I use everyday for my shower and routine stuff. I'm in and out of there all day long. It's been 2 years and I'm not constantly cleaning the floor. I picked a gray that wouldn't stand out too much and would blend with the various grays in the tile. I sealed it myself (two coats) when it was new, but nothing since. It looks the same today as it does in this picture when it was brand new.

That color will show dirt and stains. Cement grouts are absorbent. There are some that are stain resistant and you can also seal for protection.

We used Mapei's Frost (which is lighter) for a shower floor 2 years ago and you can definitely see darkened grout in the place where I stand in the center of the shower. Apparently the bottoms of my feet must be dirtier than I realize. (Keep in mind I mostly just walk around the house all day on carpeting and clean floors and the bottoms of my feet aren't black or anything.)

The darkened grout finally started bugging me enough that I went at it with a grout brush and a neutral cleanser, but I didn't get it all up yet. If I had to do it over, I'd still go with Frost because it was the best color to go with my shower floor tile. I just need to be more vigilant about scrubbing it and not simply doing a quick wipe down.

We used Warm Grey and I found that after a couple of years, it turned darker grey in front of the sink where everyone stood. I meant to soak it with oxyclean or something to try to get it out, but we ended up having to redo it again due to an insurance claim.

daisychain01, trying using barcleaners powder can get at any grocery store. Its amazing at taking out stains and does NOT scratch.
