Installed some Saltillo tiles. I lightly sealed them prior to grouting. Then grouted. The person who was supposed to clean up the grout behind me, didn't do a good job. Now a week later, there are grout streaks across the face of the tiles. How can I remove these grout streaks?Any ideas?

linaza (Linseed oil) or muriatic acid

Linseed oil (someone suggested) but I only find it is used with window glazing compound.---------------------------------------Q. I have heard that muriatic acid will remove cement that got brushed onto a patio when the bricks were remortared. Does it work? How is it used? And how long does it take to remove the cement? R. MURRAY CAMPBELL, CohassetA. You heard right, but your other questions are interesting because there are no directions on the acid bottle as to how to do the treatment. Muriatic acid attacks the lime in cement and mortar, and that is how it removes it. How to do it? Mix the acid 1 to 1 with water (pour acid into water; doing it the other way will cause splashes, not a nice thing with acid. And, as with all acids, wear skin and eye protection when working with them.) Brush on the solution with a paintbrush or pour it on the smeared cement or mortar. It will fizz up for a few seconds; when the fizzing stops, rinse. Scrubbing with a scrub brush or wire brush will help remove stubborn spots. Repeat as necessary. Let the rinsed area dry off completely before repeating.Incidentally, you can do all this the day after the work was done, or 10 years later; time is no factor.>>>> unless it's been sealed over

Try using white distilled vinegar, muriatic is
probably to acidic and can erode the saltillo.
The vinegar is much safer and can be used to
remove grout haze safeley most of the time
