PROSOCO O&G Stain Remover

This is a product that I had not used before - So I purchased it for testing -- I own and operate a Landscape construction and maintenance Corp -- We do hard-scapes - Pavers - Concrete Etc -- Prosoco is a great company with really effective products - been using Vanatrol for years ! This Works ! -- Not on everything though - Oils - No problem ! A couple of stains it did not remove - But they were old and set in - So , the resent type stains it did an amazing job -- I believe its going to make me a hero soon ! Getting stains off of patios and driveways are one of our specialties -- I'm going to make money with this ! If you do not have Vana-Trol by Prosoco as well -- Do yourself a favor -- Get it !!!! Rust stains ? Wash em right off ! Im not joking here -- All those Glaze-n-Seal Products Etc. are junk -- They actually do more damage due to the Phosphoric acid base -- Thanks !

IT DOES WORK on porous stone. Expensive - yes but so is a Bluestone patio. Had a tree removed and the saw left a bunch of oil stains all over one section of the patio. It looked pretty nasty and I tried ammonia and soap (dawn) - no results. Pressure washer on low - nothing. Tried a "liquid" poulstice - which did nothing.This worked perfectly and in high temps worked within about 8 hours. You don't have to use much just enough to cover the stain. Be patient and let it dry to the point of cracking. Scrape it off and vacuum - do not wash until the chips are gone - they hold the oil or stain. One or two treatments depending on the stain. It removed even a couple of year old cooking stain with two treatments.The only thing you do have to do is pressure wash the area after removal of the crust. It will look like white "stains" but once its washed the stone looks like new.This brand does have amazing pro level products. Used them before to remove a over applied sealer to my Absolute Black tops which looked etched which was the sealer 511 Impregnator being etched. You shouldn't seal ab black - its extremely tough without a sealer. Prosecco makes a sealer remover which is normally removed by chemical stripper. I have marble next to the ab black and that would ruin it. Expensive - 200 per bottle but it worked without damage.

I was immediately impressed by the super fast shipping on this product. I received it the very next day after placing the order. I've tried poultice cleaners like this before with very little success, but was tired of seeing ugly oil stains on our driveway and haven't been able to clean them with anything I have around the house. Our driveway was poured around five years ago and the oil stains were there for approximately one year.I waited for a day with relatively low humidity and poured the Oil & Grease Stain Remover out to cover the stains completely. This was around 8pm. The next morning I could see that the poultice had really dried a lot, but I wanted to give the product some extra time to work. I left it on until around 2pm, when it was bone dry and very cracked from the afternoon sun exposure. I expected to have to do more than one application, but for our concrete it pulled all of the visible oil out on the first try.I've heard that sometimes oil can continue to migrate to the surface, days or weeks after stain removal, but luckily I bought the gallon size and have some left for a second application in case that happens. Overall I am very happy with this product. Even my husband was impressed and that is a rare event!

Product was easy to use. My car fluid stain was large and the one gallon container only covered about 2/3 of it. Left it on 24 hours, with good weather conditions, and it made minimal to no change to the stain.

I can't believe how effectively this works. I have an older vehicle that likes to leave dribbles of oil on my paver driveway. I was quite worried that I wouldn't be able to get them out of the driveway, which we had out in a year ago at a very expensive cost. I applied per the instructions and washed it away with a pressure washer a few days later and no oil stained was left to be seen.I used a spoon as one other reviewer had mentioned since I was dealing with minor drips not a large spill. In other areas where the oil stains was smeared because of the wheels running through fresh oil, I used a paintbrush to smear the prosoco over the stain. That worked out well too. I also tried it on pollen stains from my oaks, but unfortunately it does not work for that. I don't hold that against the product because it wasn't advertised for that, I was just hoping it would work.Overall, I am very happy with the results and I have much better peace of mind knowing that I have a solution in hand for the pesky oil stains that will continue to come up.

Cannot recommend this product enough, does exactly what it says.

It’s the only product that works

On the bright side, it definitely got the oil up and I no longer have dark stains on the light colored concrete. Unfortunately, I now have white stains on the concrete. I live in a desert climate so we do not get much rain. I’m hoping the next time a good rain comes through. It will wash those spots down a little bit but right now they are just as visible as the oil. That was unexpected.
