I have these.They cut through soap scum pretty easily; far better then the other generic green pads that I had. Did well on the tile floor also. Also I noticed a difference in texture as these are more rough, vs smoother and compact.
Thought this was a fake grass door mat from the pic
SAME! I came to comments just to say this 
Also same!!!
Also same. I would buy one of those to clean boots at my garage door.
The resourcefulness of a 3m style scotch brite pad like this is endless
I use the white ones for dishes, countertops and the like . The 6 x 9 pads go along way once you cut them up.
Woot buyers, if possible please procure the Scotch Brite/3m 07445 white pads ( or Amazon commercial ). Thanks.
Got me, too!
You can really clean up with this deal!
Does this come in a 5x7 for my patio?? Whoops, it’s not a grass rug like I thought…
