This Frosch Natural Bio Spirit Glass & Multi Surface Cleaner is one of the best spray cleaners that I've used. It actually cleaned my light ivory kitchen grout. I sprayed the grout, waited about a minute, and then wiped it with a microfiber cloth. A good amount of the dirt was removed. I sprayed again and then used a toothbrush to remove all the dirt. This was the grout in front of the kitchen sink tat hasn't been scrubbed in ages, and gets dirt from the porcelain tile mopped into it all the time when the iRobot Braava or I mop the floor. I've never used a spray cleaner that worked so quickly.

It also cleans glass windows and mirrors and leaves them sparkling. No residue is left behind. It's great to have one cleaner that will go from floors to white cupboard doors to glass and do an excellent job at each. The only criticism is that the smell is kind of chemical-like, even though it's advertised as natural. It's sort of a pine smell, but not strong enough to be irritating. It doesn't bother my skin when I use it.

I love this cleaner and will continue to order it.

This product should rate 1,000 stars !! It's simply amazing. After going through my graveyard of non-working glass cleaners, I wondered why I even tried anymore. Then, I thought, well, one more try, you never know. I hit the nail on the head. Perfect, and I mean , perfect glass cleaner. I was so happy with the performance, I went tearing through the house, using it on everything. Everything I cleaned with it looks like it's been washed and waxed to a high shine......no dull film, no streaks. I used it on my garage windows and I can honestly say, you can't even see the glass it cleaned so well..........crystal clear. I rather pay more for a product that actually does what it says it does, then bargain cleaners that do nothing more than make a bigger mess then you started with. And, no horrendous smell either, which is only an added plus. The big plus is that it's not a chemical smorgasbord. I can't say enough about this product.

Our bedroom closet doors are giant mirrors, they seem to get 'cloudy' within a few hours after being cleaned, we are no longer spring chickens and cleaning these things is a real chore, so no one can imagine how great it is that this glass cleaner REALLY works! I cleaned those mirrors, it must be about two months ago now, and they are STILL as clean as they were the day I cleaned them!!! Needless to say I guess that I cleaned everything else with this same stuff and got the same results, sounds silly to brag about a cleaning product, but try it yourself and see if you disagree!

I put one in the kitchen and one in the bathroom and use them for different kind of surfaces including glass. Very practical. Do not smell as toxic as a regular cleaner. However, the smell is rather strong. Cleans better than a similar product from Method, but also smells stronger "‹in my opinion.

I bought this a few weeks ago and it worked great to make my auto windows streak-free. However, I wanted to wait a bit to see if the inside would later turn streaky, as that has always been the problem with other glass cleaners, as I live in a humid climate that seems to cause this to happen. It has been right at a month, and the inside of my windshield is still crystal clear. Time will tell if this remains so over the long haul, but this is hands-down the best glass cleaner I have found thus far. It is a little pricey, so I won't be using it as a general household glass cleaner...but it is definitely worth the price as my go-to auto glass cleaner.
