That is when the can is new (unopened), two weeks after this can was purchased from Fry's Electronics there was no moisture left anywhere in this can. And yes after taking a wipe out the cap was closed tight. Also even when the wipes were wet at the very beginning, a wipe will completely dry out in about 10 seconds after taking it out. Endust wipes also leave very visible streak of residue. And if that is not bad enough, the wipes also leave behind an enormous amount of lint particles, so after you have "cleaned" with a Endust wipe, you still have to clean your electronic/s
Even two months after purchasing this Windex wipes from the local Ralphs grocery store, they are still well moist. The Windex wipes tent to leave slight streak of residue on the screens of electronics, as well as break some tint particles loose.
