Used Groutmaster to get it cleaned, let it sit for 10 min and cleaned behind it. Have tried to continue to clean with water and let dry, had a white residue in some areas up under counters and such. Tried more groutmaster to see if it would budge and it helped a little bit. The floor was not like this when i started. Tried kick acid, and neutral cleaner. Have tried to call truckmount forums shop @RobAllen and send message but no response either way. Any ideas, i am putting epoxy on tomorrow but need this cleaned first.
