Seal It GreenXtreme Grout and Granite Sealer-Eco Friendly Deep Penetrating Protectant-No More Mold, Mildew Or Food Stains, for Those Who Like Clean Surfaces But Hate to Clean Them. Protects for Yrs.

This product is literally awesome! Works way better than hoped. Was extremely easy to apply on grout of new kitchen floor tiles using a foam brush. Worried about possible MCS reaction before use but the very very light scent went away quickly and was not an issue at all. Kitchen floor tile installers had their doubts and wanted to use some nasty commercial product. SOOOO glad we used Seal It Green instead and will brag about it to them when they come back in the spring to do the bathroom floor. Since applying, the grout still looks beautiful despite numerous spills and washes. Seller was great to deal with - very helpful and friendly. Would absolutely recommend this product and seller.

Edit: It's been a while now since I applied it and it's still keeping the staining away.I didn't use this on grout, I actually applied it to my white enameled cast iron kitchen sink instead. Why? That white enamel on the cast iron looks amazing in the kitchen but one thing I didn't count on was how fast it yellows and looks gross over time requiring me to furiously scrub it and even bleach it all the time as I think that the enamel is slightly porous or at least bumpy on a microscopic level and just all the food junk that ends up in the sink causes it to look bad over time. I'm hoping beyond all hope that this sealer can prevent this from happening or at least extend the deep clean intervals...I wasn't willing to use traditional grout sealer on it because I've used that stuff before in our stand up shower in the basement and I thoroughly did not enjoy the process as it was EXTREMELY toxic smelling, I felt like I took years off my life sealing that shower with the traditional aerosol stuff and I have not had the bravery to redo it again. This stuff, if it it works, is 1000% better... pretty much no smell at all, let alone a toxic smell... it sprays on no different than a mild cleaner. You let it sit for 10 minutes, wipe away the excess and give it another go... there is really no skill involved and it didn't change the appearance of the sink at all really, it might be SLIGHTLY shinier than it was before but that's it, or it could just be because prior to using the sealer I cleaned the heck out of it.If long term I don't notice any difference, I'll come back and update this review, but just based on my experience of actually applying it for now I'm giving it the benefit of the doubt and can say that applying this stuff is a dream compared to the other types of sealants.

This sealer is fantastic. Easy to use and water beads up so I know my grout is sealed. Just be sure to clean and dry the tiles before and after spraying. Excellent product.

Water should bead on the grout. Did it twice and still did not work.

Its non toxic.Easy to apply.Dries pretty fast.Does not stain but must remove excessive.Bottle is enough for a standard size bathroom.I gave a 2application... instructions say 3 but it worked good with 2.Very pleased.
