Glass Polish 6 inch (150mm) SCRATCHLESS Professional Scraper for Glass, Windows, Tiles and Any Smooth Surfaces - Comes Fitted with Stainless Steel Blade

I tinted windows inside homes for several years, the glass would need to be perfect or you would see the dirt in the tint. Best way to wash windows is to use a 6 inch blade with a slightly soapy spray bottle. Spray window with soapy water, scrape with blade Spray again and squeegee Dry edges with paper towel The window will be cleaner than any combination of paper, cloth towel etc you use. Here is the type of blade I mentioned: https://www.amazon.com/Glass-Polish-SCRATCHLESS-Professional-Stainless/dp/B08W1TXL1L/
