Rated 4.0 out of 5.0 by dmcc280z Probably Great on stone, fair on concrete.
The Granite Gold Stone Wash product is pretty simple to use; however, it does require a bit of scrubbing with a good stiff bristle nylon brush. I used it on my patio built out of individual concrete paving stones. In all fairness to the Granite Gold, the paving stones have been in place for 20 plus years.
The cleaner went on with no problems, but it seems to dry rapidly in the heat. It is probably best to use the product on a cooler surface. I scrubbed after 8-10 minutes and rinsed with a separate hose. The surface looked a bit cleaner, but not a dramatic difference. The second application looked a bit better.
I used it on the concrete landing and step going to the patio and had a better result. This is a single poured slab surface and there is a definite difference in the surface appearance. As indicated earlier, this is probably better on set stone or a contiguous surface. The paving stones presented a difficult choir to prevent the sand and dirt washing up from between the pavers.
I am going to use it on the front walkway from the house to the sideway. This is a single poured concrete path, so I should have a result similar to that on the back steps.

Rated 3.0 out of 5.0 by Mamajane1234 A little disappointed
I was a little disappointed in this product. I knew that the battery acid stains probably could not be removed but was hoping that the green algae/mildew would come off. I used it as directed, let it sit a few minutes, even scrubbed with a brush and it seems like all it did was spread the green out. I even went back to the green area and poured on full strength and scrubbed more with the broom but it still didn’t get it. Maybe with a lot more elbow grease, it would come off but I just didn’t have time. I will give it credit for lightening the green and making the rest of the patio lighter where just every day dirt and grime were. So if you don’t have real stains or want to put in the scrubbing this is probably a good product. Like everything, the more you use it, I’m sure the better it will make the concrete look. I think I was looking for a miracle that was not a harsh acid. I am happy that it is safe - Non-toxic, Non-acidic, pH Balanced, Biodegradable, No phosphates or ammonia and will not harm plants, pets or home exterior. It was extremely easy to use - hook up the hose and turn the top to rinse, clean or off.

This cleaner is very easy to use. Just attach to garden hose, and switch to wash and rinse! Granite Gold makes safe cleaning products, so I do not have to worry about damaging any of my outdoor surfaces or plants.

Ordered to clean my backyard walkway and walls which worked but not as well as I'd like. On walkway once the cleaner was sprayed I used a broom to remove more difficult stain, which worked. One bottle covered a large area.
It's great the way the sprayer works, only I would have put the shut-off value in between the cleaning dial and rinsing cycle.

Rated 4.0 out of 5.0 by Richard Renew the coplor appearance
I used the Granite Gold Outdoor Stone cleaner on the front step 9 x 6ft tile border with broken tile random pattern and 6 x 6ft back step. Front with full sun and faded colors and back with almost no sun, green after a 3 or 4 days of rain. I had good results with the color restoration and cleaning. Although I don't have any fir pits or stone BQ areas I would certainly reach for this product. I can't wait to try it one the driveway even though the mfg recommends a more aggressive solution. It is too easy to use not to try to reduce the stain from the crape myrtle during the fall. Guessing 2 or 3 times during the fall while they are dropping

I would recommend this product but not for the outdoors but for the indoors. I would love to use this on my granite counter tops and the tiles in my shower, the scent is really nice and I wouldn't mind having it linger in the air after doing a good cleaning.
I used this product as recommended on outdoor surfaces such as the driveway, walkway, stone borders as well as ceramic pots. We have had a very rainy season and like every year at this time these areas need a good cleaning. I was disappointed this product did nothing to clean the surfaces that were much in need of cleaning.

We have a beautiful wrap around porch on our home...it's why we bought the house. We also have a daughter who is an artist. While creating one of her masterpieces, she got paint on the porch. To make me feel better, she turned the paint drips into a big heart. Good intentions. Long story short, Granite Gold Outdoor Stone Cleaner got it off - 6 years later. The rest of my concrete porch looks brighter and cleaner, too. So happy with this easy-to-use product.
