Amazing! We just rent what was supposed to be a "Luxury apartment". I was shocked when I saw all the tiles had grout so dirty that I was at a loss as to what to do. Your experiment showed me and now my tiles and grout look astonishing. Thanks for the head's up on this one!

Thanks for the info. I just bought a house that has the dirtiest kitchen floor I have ever seen. I was going to replace it but have decided to try to save it and just clean, clean,clean! I'd rather spend the money on quartz counters..lol. Your post has encouraged me to use the Oxiclean method and save my tile from the dump.

I agree with Ray: after using a cleaner--even a vinegar spitz--it would be best to re-apply sealer.
