I agree with Ron-doesn't look like black absolute either.
Not sure what the white is but it is probably on the surface- maybe the solvent  of the enhancer degraded the dye if that what it is.
Time to get to the bottom of the puzzle-try using on one tile a marble polishing compound-don't worry it wont make it shiny-but the acid from the compound will remove the dye in most cases. Did you notice when you were working on the stone stripping that the residue was black.
I would try a 180 grit honing powder as well just to see what you get.
What does an original piece look like.

Steve,

It almost looks as if the stone was dyed and the color is leaching out. (Fading) I wonder if that could be the root of the problem. Sadly every once in a while we come across doctored stone, and of course what should be a routine service becomes everything but.

Just an observation from the picture.

Hello partners I need some help to fix this problem, about a year ago I got a call to enhance an absolute black flamed granite wall. I did it and it looked great !!! About 8 months later the builder call me cause the wall looked really bad( white spots everywhere). So we when back strip it and re-enhance it it look good for a week the white came right back, so we decide to strip it and don't put enhancer anymore it looked gray and nice but two days later the spots came back. I checked the mouisture and it is good about 4% what can I do to fix this? The dark area is an Agee remover that I was trying!!
