We live in the wet Pacific Northwest where moss and algae grows on everything. We rent a power washer every year to clean the driveway and patio. I usually shy away from soap outside because of environmental reasons. This seemed like a good option. We poured it into the reservoir of the power washer, sprayed it on the surface, let it set, and washed it off. It easily cleaned moss and algae from the patio, driveway and siding.
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.
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.

TRIED CONCRETE AND DRIVEWAY CLEANER ON PART OF MY WALKWAY TO SEE HOW IT WILL REACT, ALTHOUGH I ALSO USED Simple Green 128oz Heavy Duty Cleaner and Degreaser Pressure Washer Concentrate ON ANOTHER PART OF WALKWAY WITH GOOD RESULTS. THIS CLEANER DID NOT PERFORM AS WELL AS DEGREASER, BUT IN FAIRNESS I GUESS IT DEPENDS ON WHAT TYPE OF GRIME AND GRIT IS ON THE CONCRETE.
I am really happy with this cleaner. My patio probably hasn't been cleaned in 15 years and after trying just a small patch once over, I can see this product is going to do a bang up job! Have posted a pic to show you the difference. I do recommend! I like it especially because there is no bleach in it and it won't hurt my lawn or plants!! Very important! It's a big jug and makes alot of cleaner.
PRODUCT REALLY DID NOT DO WHAT IT WAS ADVERTISED TO DO -- REMOVE DIRT STAINS ON GARAGE FLOOR. CLARIFICATION -- I USED THE MANUAL METHOD IN LIEU OF POWER WASHER.

My grandson was working on his car and had gotten oil on our driveway. Unfortunately this did not clean the oil that was on our driveway. We had to have it professionally taken care of. This product did not touch the oil issue.
