What is the best way to clean granite floor tiles?

Granite floor tiles! I didn't know you could use it as a flooring ver exciting news for me. I thought it was only for counter tops

Best wY I use to clean my granite is with a cleaner special made just for granite and a plastic putty knife to scrape ip the hard spots. Then use a polisher to buff to a shine

If for some reason you meant ceramic tile. Use a scrub brush and Comet works every time

Your problem you're facing is to somehow get a cleaning solution down between the tiles and into the crevices of the grout, and then get it back out. I like to use a carpet steamer, the kind that looks like a vacuum cleaner. These machines shoot down hot water and detergent with a lot of force, and then suck it back up. That will get all the dirt between the tiles. No hands-and-knees work involved. It should clean your tile floors nicely.

I like TileLab cleaner and protectorant available at the Home Depot. You can get it in a spray applicator and use a mop to spread it. You don't have to rinse it off because as it dries it will leave a nice shine. It also leaves a protective coating on the granite which helps resist dulling over time.

There are many good quality tile cleaning machines available in market. Buy a tile cleaning equipment with steam cleaning feature from best cleaning results.

Try diluted lemon juice to clean and then mop with clean water. Try it on a small area first. Worked really well for me and it smells pretty good too.

I would purchase a small floor steamer
