One trick you might try and this is going to sound strange but have had great luck with it.. take some Tide Laundry detergent and add some polishing powder and work this paste into a heavy slurry with your floor machine. Use a hogs hair pad..Of course try a small area first for results.  Start out with one cup of Tide to Half a cup of Polishing powder<div>

<p class="MsoNormal"><span style="font-size:11.0pt;color:#1F497D">From the pictures it appears to be a grout residue that has
attached it’s self to the tiles. If this is a porcelain tile that is
textured finish and the installer did not clean the grout from the tile this ia
a grout residue around the tiles. </span></p>

<p class="MsoNormal"><span style="font-size:11.0pt;color:#1F497D">Suggest using an acid based cleaner with a soft brush on you
floor machine. After the cleaning with the acid based cleaner you need to scrub
the floor one additional time with  Stonecare Central’s neutral
cleaner to put the floor back into a PH balance.</span></p>

<p class="MsoNormal"><span style="font-size:11.0pt;color:#1F497D">As always test an area before bidding the job to make sure this
is not an epoxy grout that is on the tile, if so you have a totally different
approach and will cost more money to remove. </span></p>

<p class="MsoNormal"><span style="font-size:10.0pt">I
am currently trying to remove stains from a new porcelain tile
installation.  The porcelain tile is unglazed, and more or less
&quot;open&quot; .  It is in a bathroom in a commercial building. The
staining appears to be coming from the grout.  The grout is black and so
are the stains.   The tiles were sealed prior to installation with
Miracle Sealants &quot;Porous Plus&quot;. The grout is laticrete perma
color.  We have tried cleaning it with our usual stone cleaner, Viper
Venom by Bridgpoint. No results. Then we tried acetone which yielded next
to no results.  The we tried Aldon&#39;s Premium Stripper (solvent
based).   The we tried an epoxy grout film remopver.  No
results.  None of these chemicals have impacted these stains. The floor
will have to be torn out unless I find a solution.  Attached are some
photos of the floor.  Any ideas?</span><span style="font-size:10.0pt"></span></p>
