I always struggle when washing my car windows. No matter how hard I try or how much I pay for an item that professes to work wonders on my car windows, I have little success getting the finish I desire. I came across these little towels and thought I would give them a try. I used one for wetting the glass and the other for drying it. Wow!! No streaks!! No lint left behind!! Just absolutely beautiful windows!! I highly recommend these detailing towels. If they ever wear out, I will run right down and purchase more.
