    Product is great!

    I highly recommend this it is a fabulous product and it really works wonders removing rust stains.

    That being said, I have used it in the past and needed some more of it and ordered it though DTS…. They never shipped it, took my money and have not issued a return. I sent several messages never to be responded back to as well as called and left messages, granted is was a small order but with we like to vet suppliers before we purchase more from them. This had to be the worst no customer service and took the funds and no product shipped.. so buyer beware shop other places to get this wonderful product;
