I bought a gallon of your M-Pro7 Gun Cleaner.  The other day I was pouring some of it out of the one gallon container into a small glass container and I see there are lots of "flakes" floating around inside of this cleaner.  What is that?  Does this cleaner have a shelf life?

Although we have customers who have used the same gallon over ten years with no complaints, we recommend that M-Pro7 Gun Cleaner be used within two years of opening the product.  The white flaking you see is “fallout” due to the change of pH levels in the cleaner.  This does not usually affect the cleaning power.  This mainly happens when the product is in direct sunlight or if the product is being re-cycled and re-used.  There is no way to mix the flakes back into the original solvent; however you can filter out the flakes and use the rest of the product.
