Cleans with no streaking.
I made my own cleaner and these cloths work great! Im so happy that I got these, no streaks, the glass is clear and cleans them faster. Worth the money.

Secret to Great Auto Glass
Awesome product. I struggled with getting clean streak free glass on my truck. Thought it was the cleaners (multiple). It was the cleaning towel. This one rocks! I've bought 4.
