Hello Brian,

As I'm sure whoever you spoke with on the phone told you, I would use either of those products with zero hesitation! Iron remover is very fickle when it comes to manufacturing the product with a consistent color, and anything from extremely high to extremely low temperature can also cause the color to be altered slightly. I can assure you that the product is perfectly fine, and that it will still be just as effective as any other bottles.

Thank you for contacting us and thank you for your business!
My gallon of NV Purge has done the same. It comes as a darkish blue but has shifted to an amber colour. It still functions the same. Having said that, my gallon of Gyeon Iron is still the same clear liquid it was when I opened the bottle.
