Who knows if this will get deleted but who here has tried 2790 made by shores best? It's pricey but there is NOTHING that I have found that cleans better on tile and grout. I haven't had to scrub a single grout line in over a year (except for when I run out and have to use viper venom or tile wiz.). I did a side by side comparison at a house today with viper venom and 2790... It made me upset that I've wasted so much money over the years on that crap.
