Rated 3.0 out of 5.0 by DIYinOH I had higher hopes
I use Simple Green for EVERYTHING and I've never been disappointed. The original SG is like magic. The lemon one is awesome in my shop, the carpet cleaner nukes doggie stains... so I thought the concrete cleaner would be similar magic.
Unfortunately, it doesn't do much better than a standard degreaser. We had an oil sensor crack on us last week, and an entire pans worth of oil ended up on the driveway and garage. This calls out oil stains specifically on it's packaging so i thought that would be a good choice.
I coated the floor in cleaner on low pressure, then used a deck brush to rub it in, then pressure washed it off with high pressure.
It removed the standing oil and grime, but did NOTHING for the stain on the driveway (unfortunately). I attached pictures so you can see for yourself.

Rated 3.0 out of 5.0 by Reshida Not the Best on Concrete...
Thanks to the builder of our home, we have a combination concrete/asphalt driveway. This concentrate is just ok. It certainly cleans, but it doesn't get the concrete as NEAR as bright as the solution used by professional pressure washers. I would still recommend, but understand, if you're expecting a miracle, it's best to hire a professional pressure washer.

Rated 3.0 out of 5.0 by kens Helps clean driveway
Our driveway gets a bit dirty from wind blown vegetation, road dirt, tree seeds, shade near bushes, etc. The only way to get the concrete color back is with the use of my Honda engine powered Power Washer. By using the narrow pattern nozzle and moving the wand slowly over every square of the driveway, the color can mostly be restored. I did this with clear water from the hose on part of the driveway and then used the "128 oz. Concrete and Driveway Cleaner Pressure Washer Concentrate" on the rest of the driveway. The cleaner only helped a little bit better than plain water while keeping the progress of the nozzle the same for each trial. The driveway is quite large because we have a three car garage.

Rated 2.0 out of 5.0 by Strato Cleans average dirt and grime but not oil spots
This product will clean average dirt and grime. It will not remove oil spots on the floor. it will lighten them up but you will be able to see them plainly . I found using a bleach will do better than this product in getting concrete garage floor clean. It did not hurt the grass when washed off. I used this full strength on oil spots , worked it in and let it sit. Power washed off with 25degree angle at 3100 psi. The area around the oil spot was clean and lightened up but the oil spot remained.

Rated 5.0 out of 5.0 by EleEng An excellent concrete and driveway cleaner concentrate for manual or pressure washer application.
This past weekend I gave our garage floor its spring cleaning using Simple Green's Concrete and Driveway Cleaner. I am very impressed with its ability to remove oil, salt, grease and grim that built up over the winter months. The product worked well in my gas powered pressure washer. Plus, instructions are provided on how to use the product manually if you have only a small area to clean or do not have a power washer. The instructions on the back of the bottle are clear on the amount of water to product you need to mix. It then describes the proper procedure for applying, rinsing, and protection of surrounding vegetation.

Rated 1.0 out of 5.0 by Ken Disappointed with it's effectiveness
When used with the power washer's detergent head, it did little to clean my paver patio. Washing it off was a job because it kept foaming up...suds and more suds. Plain water with a higher pressure head did the job. For me, the "simple green" product was a waste.

Used this soap with a 2000 PSI pressure washer and it took oily stains and mold off the concrete with ease.

Rated 4.0 out of 5.0 by steamenginesteve Beats the General Purpose Cleaner
I had a synthetic hydraulic fluid leak from my tractor that I allowed to sit on the driveway for a week because of sub-freezing temps. It soaked in more than expected and my standard pressure washer cleaner didn't do that great. I let this concrete cleaner soak and kept applying several times over an hour period. Then hit it with the green nozzle(medium angle) pretty hard. It about did the trick and my big spot has almost faded out now. I think when I do it again when the concrete is hot the spot will about be gone. I like this Simple Green product. A gallon concentrate will make over 10 gallons of strong solution for HD cleaning.
