So I cleaned 2 stories of 4 inch spanish tile, some indoor some out. The outdoor I cleaned but didn't do much of anything in regards to restoration... still lots of hard water stains that I'm told can be taken out by muriatic/hydrochloric acid (will this cause damage to my equipment?) Half of the tile was covered in some sort of wax that I removed with viper venom and I't looked good ... much oranger how I would think that it looked when it was new. The owner liked the more glossy look it had before but during the estimate pointed out the fact that they wanted the build up removed. Is there a product that I can coat the tile with to make it more glossy? The other half did not have wax on it so the stripper had no real effect on it so I only used the 12ph cleaner on it but left it very streaky. I know that the problem is mostly chemistry related... any suggestions? I worked long enough to justify the $2100 but the results are less then I hoped for. Any advice would be awesome!
