Thanks. I’ve tried fine tools (Dremel) to remove surface staining on grout lines and even razor blades. This floor however has 1/4” grout lines with sanded grout. The wider grout saw may work good.

Just remember if you try it you just wanna do it light enough to scratch and that’s it and if you have a lot of floorspace that is open and you have a mechanics creeper lay on the creeper.

Depending on how many square feet you have a little grout saw from Home Depot will remove the epoxy  or resin whatever is on top of that and will make it look good without re-grouting  whole floor.

I did it on a job three coats of urethane on imitation slate tile and Sandable  grout. 

All you have to do is scratch the surface that’s it the grout Saw does the work.

Thank you everybody. I will price out re-grouting. I don’t see any other way to get a good result.

Most likely impossible to get wax like that out-I see other discoloration as well-
methylene chloride might work- but very tedious exercise.

This sandstone is like a sponge. I can color seal sand stone?

Hi Pros,

Have this sandstone floor with sanded grout that was waxed before. We stripped and grinded and polished the floor but the grout lines are tough (pic below)
Anybody have any good ideas?
Thank you,
