You have a valid point and could very well be the case. The only thing that makes me think it’s fairly new is like I said it seems sort of moist. You can squeeze it and it clumps together a little bit. I would assume if it had been sitting for any amount of time with the jars exposed to hot or cold or both it would be dried out. It also had a very nice fresh smell to it when I opened the jugs. Also worked great today on a nasty apartment. As I said earlier worst case scenario is I’m out $150 or best case I got #32 of a pretty high quality pre-spray. I figured what the heck for half price it was worth a shot.
