Does anyone else pressure wash the exterior surface concrete areas at Cracker Barrel? I am having issues with removing black stains near the garbage dumpster. Everything goes right to that spot, and the stain is getting worse. I tried Double Eagle and F9, but it does not lighten it at all.
Cold or hot water?

Butyl based degreaser with sodium hydroxide. Spray it on, let dwell little while, brush it some, spray some more on it and then clean it with hot water. it’s nothing special. Not going to all come out first cleaning but will look a lot better.

Thanks, Rick! Is Zep a good brand?

Got no idea, have never used it, but think I’ve seen other on here that have used their purple degreaser. Or just go buy some concentrated Purple Power Concrete cleaner.

Try purple power , let dwell 15-20 min . Use hot water
Go to Walmart and get some Purple Power…it will work well for that. I have started using in on my Dairy Queen accounts and it works well and is CHEAP. I downstream it straight…for bad spots I will use a pump up sprayer with 50/50 mix. Just have to remember…you will never get all of that stuff up…it will look much better but there will be some left in the concrete. You have to temper your expectations and be satisfied with less than perfection…but then, that goes for washing almost anything.

The Purple Power did not lighten up the country food grease at all. Any other suggestions?
