Helpful hint when putting down a bead of caulk

Well, I tried this tip out this week since I am one of those "spit guys". Not dead yet after all these years! Anyway, the Windex did work well with just my finger and beads looked good. However, I did notice streaks in the surface and found that the Windex took off the wax. I had to rewax those areas around where I had worked. Besides ammonia Windex has 2 different alcohols in it. Since I like the shine my waxing leaves on my 5'er I think I'll try just water next time.
