You can try the Majestic Heavy Duty Tile & Grout Cleaner which is a blend of phosphoric acid. Remember, do a test with this solution and a stiff toothbrush or similar to see if the contaminants can be easily removed. If not, do a honing test.

Unfortunately I think the whole process got mixed up and now we need to fix it. Do you have an acid cleaner you recommend?
