Description Reviews Streak free windows and mirrors have never been easier! Use the first folded towel and wipe the glass with your cleaner. Then take the 2nd towel and lay it flat and wipe across the glass. BAM! Maybe 2 passes at the most and the surface is spotless. These towels pick up chemicals off of glass and leave them streak free. More importantly, if you care for them, there is NEVER lint, based on how they are constructed. Tip! Never mix glass towels with other towels. They may pick up lint or other products. We recommend a bit of white distilled vinegar with each wash. size: 15.5" x 15.5" 80% polyester 20% polyamide 350 GSM (grams per square meter)
