I've had the M-Pro7 for quite awhile and it seems to have thickened?
The change in appearance and thickness are from two things:
1. Evaporation: M-Pro7 Gun Cleaner over time does lose some solvents and surfactants to evaporation. Exposure to the air can also lower the pH.
2. Carbon: MPro7 Gun Cleaner is an alkali or base solution. Carbon fouling is acidic in nature. Over time, even with filtering, the carbon lowers the pH value of the gun cleaner. Once the pH falls below 8, the cleaner needs to be replaced.
