FP Plus gone bad?

[ThirdGear]

Well, basically I forgot about a jug I had with a little bit of FP Plus in it. I was going to use it but I noticed there were little particles floating around inside of it, almost like pulp in your orange juice. Anyone else ever see this? The jug had the plug in it and had a tight cap on it.

I noticed the same thing in an old jug of LC20 that I had in the garage...a light brown residue on the bottom of the jug with floating particles. I shook it up and am using it...figure it should still be good (recently purchased another gallon of LC20 which I'm using again).
