2) Be sure to load glassware tilted in a position that will drain all surfaces so as to avoid any upturned “cup” that will retain wash solution and carry it in the rinse cycle where it gets redeposited all over other glassware – a classic example of this happens when you load a graduated cylinder straight upright and the base of the cylinder holds wash solution – it is best to load graduated cylinders at a bit of an angle.

I would like it to be able to be used like a dish soap as we soak our glassware for short periods of time. It is importance that the cleaner to be food-grade as we process flavors for food.
