So here we go:
1: So the first step in the process to install the window tint was to thoroughly clean the inside of the window as to remove all dirt, dust, and debris. I first used my soap/water mixture and sprayed it over the window liberally. Then I used my hard card wrapped with a paper towel to remove thhe preliminary dirt and dust.
2: After cleaning with the soap/water solution, I then moved on to the alcohol/water solution to strip any remaining dirt and dust from the window. This is why I needed two different spray bottles for this install. Spray on the alcohol/water mixture then take a razor blade
(SINGLE EDGED RAZOR BLADE RECOMMENDED) on an angle and clean off the window of your mixture. Make sure you scrap the window with the razor blade at about a 45-60 degree angle. It removes the risk of scratching the window if you were to use it perpendicular to the window.
USE VERY LIGHT PRESSURE IF USING A DOUBLE SIDED RAZOR BLADE
3: After completing this step use a microfiber or other lint-free cloth to finish drying off any remaining water.
Now the window is clean and ready to install the tint.
