What a weekend
I tried:
Non diluted:
Ammonia
Simple green
Lysol all purpose cleaner
404?
Greased lightning
then finally Purple Power
Purple Power was able to barely get it off---I scrubbed with a stiff brush for hours and hours before it finally cut this crap off.
I even tried
Menzerna IP and that just made a mess.
Don't ever EVER use Mop-N-Glo for the love of God.
I'm going to give them a call today and wear their a$$es out. It nearly ruined my 325 squares of marble tile.
