We have super hard water. Despite soaping to degrease the lenses, our water never just sheets off like soft or distilled water does on a really clean surface. It beads up and leaves deposits when droplets evaporate. So step 5 is problematic for me.
After the rinse, I set the glasses down on a paper towel - temple pieces extended as if I were going to put them on. The lens frames rest on the paper towel, their lower parts in contact with the towel.
I use canned air to gently drive droplets down front & back surfaces to the bottom of the lenses. They then generally wick away into the paper towel, or else evaporate at the lens/frame interface. No need for step 6. Takes about 30 sec, leaves no spots on the lenses after.
