Hello. I am new to the business and through word of mouth I landed a potential job with a pretty large construction company in my area. They recently restored an old high school. The lower section of the building is covered in what seems to be brick mortar. I read muratic acid and some scrubbing will do the trick but I can't seem to find it in my hardware stores. There's a chemical supplier not far from me and they have a product that may do the trick. Grout stain issues - Aldon Chemical for ceramic tile/stone/brick: care-cleaning-protection-maintenance-problem solving restoration. <---LINK
I have attached a few pics of the mess. Any help would be appreciated.
Thanks
