This heavy alkaline cleaner for concrete and tile/grout has been mentioned here before I'm sure. I just purchased a case recently and this stuff is awesome. Best cleaner for tile/grout I've ever used, it etches the grout as well.
Hey Albert, do u have to acid etch after the Powermax mix? The 2790 saves from acid etching grout, from my results so far. I was boosting Stone Pro Deep Gel with Oxyblaster or OSR with hydrochloric acid etching after...this stuff saves me 1 step and having to breathe hydrochloric acid which has probably shaved several years off my lifeAlbert Lazo said:I've used it and it works good. However I'm not sure if it's any better then Powermax boosted. I don't know what's in it but you can see some sizzling going on when it's on the floor.
I've had it reduce the sheen of some marble we cleaned some time ago. It had a high hone finish. I was to monkey pad at 800 grit afterward so it did not matter. Even on a test limestone tile honed to 250 grit it etched. The test was up to 12 to 1. The thing is that even some honed surfaces have some kind of sheen and this stuff may etch it.

you don't tape off or protect surrounding areas? a "product" that cleans tile/grout and doesn't damage carpet or surrounding areas probably is a half assed "product"...and wearing gloves is a must...just my opinionGeneMiller said:a ph that high can damage other surfaces especially your skin. i prefer a product if it accidentally gets on a carpet or other surfaces it won't damage it.
