I am currently working a second job as a floor man in a business building. I have 48 floors to cover. Since I only do the bathrooms it's not to bad. But I am having a problem with the grout. You can see in some of the sections that the grout is supposed to be pink instead of black. We have purchased an acid based soap that works somewhat but is rather expensive and rather toxic to breath. So looking for a cheap and healthier way to do this. Any ideas?
