I have been getting a lot of calls about cleaning Mannington Adura and DuraCeramic vinyl tiles with acrylic grout

It is installed using pressure sensitive adhesive. Look at the grout lines really close you find that it isn't grout at all but part of the tile made to look like grout. Tell by the normal crack that you see from the tiles shrinking on two sides and the other two sides you won't. Number the sides clockwise 1,2,3,4. As an example sides 1&2 the grout will be attached to the tile you have numbered. Sides 3&4 you will see the crack and the supposed grout is attached to the neighboring tile.
