Super Concrete Dissolver 22oz Foam Spray

So back almost a year ago my I noticed some, what I thought to be as water (hard water/calcium) dripping onto my car in the parking garage. No big deal I thought as I had washed it off before and there was not an issue. Well I left my Mustang parked down in the garage for a few months and when I went to wash it this "mystery substance" would NOT come off on my car. I tried everything, warm water and soap, letting the spots soak, going to car wash. I also took my car into a few detail shops and they were confused as to what it was.I went back down to the parking garage and noticed there was a massive crack in the roof and that when it rained it would go through the cement and then drip onto the exact parking spot where I was leaving my car. So I found one detail shop who could get it off but they wanted $300 dollars to remove it and then wax/polish the car. I avoided doing it because I did not feel like losing my car for a whole day as that is about how long it would take them to do the job and get my GT back to me.Few weeks ago I was doing some research and youtubed how to get cement off car and found a video that was showing this very product. After watching the video I went and bought this right away. As advertised it worked amazing! You will spray the product on the spots effected and after a few minutes you will start to see the cement come off in small clumps. Now depending on how bad the area (the area below my quarter window as shown in the photo) will take multiple sprays and a lot of patience. I had to spray, let it work its magic and then wash the spot with soap and water, and redo over and over as this spot was pretty thick. The other spots that were not as bad (driver side window, rear end of car) only took one spray and then I wiped it off with soap and water.This did NOT damage my paint or case any fading or rough spots. However it is VERY important you do not let this product dry on your car, keep spraying and keeping an eye on it. Wash the product off and reapply the spray. By the time I was done (took about an hour) and I had cleaned the car and it looked brand new! The very next day though (where I dumped out the bucket of soapy water) you could see a lot of dried cement. The drain was caked in the cement that came off my car but that is not a problem of mine so make sure you do not dump this somewhere noticeable. Great product worked perfectly easily a 5 out of 5. The only con was as someone said the bottle did show up with the top not securely sealed and some of it had leaked in the bag and that is exactly what happened to me as well...frustrating that I spent 25 dollars and some had leaked out. However I had enough to get the job done, and some left over incase this happens again or I noticed a spot I had missed.

Only removes very light concrete splatter. Does not work on normal concrete splatter.

This is by far gonna be the best review I have wrote for anybody. My product came in today, I was excited to use it on my truck, I have a Nissan frontier that’s in mint condition, and it had concrete splattered on both sides more of the passenger side than the driver side. I was concerned about using anything for I made phone calls to all the detail shops around town and they sat there and said basically time and money to get it off it would be easier to just get it repainted. So I’m buying this product I was very hesitant, but I also took a chance and bought three bottles. I sprayed it on, gave it to 10 minutes, look to see if the little spots were coming off, so I took my thumb and just rubbed it and it came off immediately, so I continued keeping everything wet, don’t expect it to just spray on and spray off do what it says spray it continue spraying at keeping it wet and it will come off. After you do a few abs and you give it 20-30 minutes, all you need to do is spray it with your hose. Make sure you got a good hose that has pressure, and not a pressure washer just a normal household hose, and just spray it right under get about a foot away from it and spray. This is by far the best product I have ever purchased through Amazon. You have saved me a bundle of money and I greatly appreciate it. Thank you so much

I got concrete on newer pickup from road construction. Assumed it was just mud, thus didn't hurry to wash it. What a mess. Took some off with vinegar, which helped but not a lot.This spray made removing light streaks of concrete fairy easy, but won't just wash off after soaking with remover. I used my finger nail and wiped with rag. Careful, rubbing concrete on auto finish is going to scratch....Lower surfaces that r coated with concrete, the spray softens the concrete. I just worked it off layer by layer. Remover application after application.This is still a work in progress, just working on it a hr at a time. In an hr may only clean a few sq in of the heavy caked on concrete. Could easily take 40 hrs to clean just the outside surfaces. Multiple bottles of remover. While this is not a glowing result, compared to everything else I have tried it is great!Not sure what to do with wheel well liners. May just leave it, replace them......actually going to try a grinding wheel on drill...what could go wrong?UPDATEI have discovered that keeping an area wet with the spray for 45 minutes will soften a lot. Still won't remove thinker layers of concrete in one 45 minute application. To keep it wet that long on vertical surface takes multiple applications. This is a slow process, but does provide a solution.After man days of work, 3 bottles of dissolver, and $85 at car wash; most of the concrete is off the truck. Running board bottoms still solid concrete. Wheel wells not quite clean, a few spots left on painted finish. Wish I had taken b4 pictures, just imagine a truck driven on mud road a 25 mph, but concrete vs mud. I did it in town on road construction vs mud road. Thanks Port Aransas.
