So I'm trying to understand the concept of grout cleaning. I seen those white fill-in-the-lines grout filler products which look like they just paint on top of the grout lines. In this case if dirt is in the grout, it just gets painted over which is disgusting. We cleaned a restaurant floor last night with degreaser, a stripper and grout brush on rotary buffer machine. I cannot distinguish what worked better. Does anyone know if degreaser or stripper works best for tile and grout like this? My partner and I hand scraped every inch of this 2000 sq ft floor. It was so bad it seemed the grout needed to be scraped first and the floor cleaned afterwards. I almost wanted to charge an extra $200 on top of quote to scrape out the grout. The scrape work was very intensive. Now can anyone tell me if we are cleaning this right? Is this dirt we are scraping out of the grout or are we damaging the grout? Is this black grout or is this just dirt buildup in the grout? I have no idea but this process took a long time and will need a new technique or brush to get this up. The black stuff was so hard to scrape out in some areas it made me think I was damaging it. Now the last picture in the post is the final product. So can someone tell me if we damaged and pull up all their grout filling or was it years of caked up dirt and grime? If so how we clean this better instead of hand scraping? I was thinking of a harder roatary brush such the MAL GRIT Black Bristle Brush. I want the hardest bristles because that grout or dirt was hard to pull up. Only came out with metal scrapers and dulled the hell out of them too.
