It actually cleans ground-in dirt from TRAVERTINE... with lots of elbow grease!!
I didn't know going in, when I had my travertine installed 2 years ago, what a frickin' pain in the a** this stone would be to clean!!  I have tried different methods with the same ground in dirt left on my floors and looking like crap!  So I started doing some research and came across this product and it seemed to work well from everyone's reviews.  What did I have to lose?, so I bought some.  I followed the directions for mixing, but found that just putting the concentrate directly on the floor worked better and then just let sit for about 3 minutes - then get out the scrub brush and scrub and I mean scrub!! It lifted this 2 year old dirt off the floor...amazing!!  Is it back to 100%?, no- but at the very least its 80% better!!  I think some people who reviewed this product thought it was a magic cleaner, just putting it on and wiping away the dirt...let me tell you it is not- you need to put some work into it for the desired results.  I recommend to just focus your scrubbing on the really bad spots!  We have a large collie and he doesn't help matters either just laying in his two favorite places on the floor, let alone the dirt he tracks in from outside.  There is one area of heavier traffic that I know I will have to do a second time, but for the money we spent on those floors, the effort, elbow grease and sweat is definitely worth it!!  I will buy it again and will recommend this product!!
