As you know, cleaning glass can be more challenging than polishing the paint! In our never ending quest to achieve the perfect glass technique, we’ve found that this incredible tight weave is incredible as the final wipe to eliminate streaks. This process is “grippy” as the glass becomes clean during the final wipe. This material can and should be used to clean sunglasses, E-screens, windows, and mirrors. Best to pinch the material between your fingers during the wipe as it will be grippy as it removes the last layer of streaks. Game changer for perfect glass. These come in 2-packs 20" x 20".
