I made the Q-tip (see attached) and used a glass cleaner only moistening it a bit. The foam inside and the cloth held the liquid quite well without releasing a single drop. The driver side glass was really dirty. I went in a second time with only dry cloth to wipe off any moisture.
It sparkles now, except for the very edges. The tip should be about 10 inches, if longer, the back will interfere with the ABS plumbing behind the driver side lamp.
Now I only need to check the alignment.
