What is this?

I just received a call to look at a tile floor with black marks on it.

The person that called me is a friend that only does hard surfaces.

He said that they tried several chemicals and a 175 floor machine, but no go, he also tells me that it looks like skid marks from shoes, a cart or sometime like that.

I get there and the construction company forman says that several peoples have tried and can not remove any of the black stains.

What would you try? I do have the answer.

They look like scratch marks .. try some soft scrub or comet cleanser and a scrubbie

 

[BIG WOOD]

Have you tried a paint remover?

 

[Mikey P]

I agree, some type of polishing creme under a hogs hair pad

Looks like the type of scrape marks left when something metal gets dragged around on the tile. I agree with trying a cleanser like Barkeepers Friend with a scouring pad. Of course test in a small area.

 

[Mikey P]

Aluminum residue I'm betting

Todd is right. Mike might be right too, but don't anybody tell him.

The person that called me had tried floor stripper but that did not work.

I did try a little POG but that did not work, so the only other thing I had on the truck at the time to try was rust remover and POW that took it off with no problem.

With that, my guess is it must have metal in it.

Grab a Mr. Clean Magic eraser for just a test also if don't have the other items mentioned....

Be careful with rust remover. I did that one time and it ended up etching the face of the tile.

Yep.

We did try a Mr.Clean Magic eraser but it did not remove any of the marks.

I will not be doing this job, I just went over to help see what could be used to remove the marks. Unless someone comes up with a product that would remove with out any damage to the tile.
