I'm using Elvanol 85-82 dissolved 10-20% in distilled water with 10%91%I Isopropyl alchohol and about 2-3% glycerin with a few drops of carwash soap as a lens cleaner.
The viscosity and drying are pretty good but when I lay it down on glass it sometimes tends to bead up a little from too much surface tension ( I think). Interestingly it beads less as I repeat the process of cleaning so it appears that initially whatever oil there is on the lens is probably contributing to the problem. Moreover, I cleaned one lens carefully with methanol first and it doesn't bead.
I'm wondering if increasing the amount of carwash soap will help this problem or if it might be one of the other ingredients I need to increase or decrease.
