    All season I have been using Puremelt with CMA and it has been a great product until the last pallet I bought. Either they changed their mix of blue in the product or someone at the factory messed up and just about tripled the amount of blue in the ice melter. This product stained the concrete blue on a few of my properties and not I dont know what to do. I went there this morning and the concrete was dry and you could still see the tint of blue. Any suggestions? I have stopped using the product by the way.

    Have you tried to rinse it away with a garden hose? I know most are turned off, but it's a thought. I'd get on the horn to your supplier and if they don't help go to the manufacturer. It very well may not be a permanent stain though, if it washes away no harm no foul. BUT they should still replace the product you already have.

    Find out if it's Prussian Blue--a very common blue dye in salt. It's water soluble and should rinse off, but you might need high-pressure to get it 100%.

    How old is that concrete? The surface is in terrible condition. Have you been using that product since new? I'd look into switching to regular rock salt....

    Use a torch. Then all you have to buy is propane or mapp or asedyline and o2. Are your customers complaining???????

    Just bust it up and re-pour it with with hydronic piping. Problem solved, and bill accordingly.

    Not sure how old the concrete is. Concrete is not my department but why do you say its in horrible condition? It doesnt look like that to me. (Im just trying to learn your point of view so I can better understand, Im not questioning you)
    Yes, they are complaning.

    I test concrete all summer, and am around concrete all time. If that's brand new concrete, it would be a problem, but if its 10 years old, it's showing normal wear.

    You had a bad batch of salt. After a couple of good rains it should be gone. Reason why I always use rock salt but then again I hardly salt concrete driveways. Salt is never good for anything. Over time salt will speed the hydration up in concrete even after its been set for 5 years, which over time will crack. MANY dams across the world have waterline going through the concrete to help keep it cool to slow the hydration. I've read articles on the Hoover dam stating that they don't expect the concrete to be cured 100% for another 75 years.
