Bart,I wasn't sure if you were talking inside or out, tinted or not. The vinegar is good on non-tinted windows. Iwould use a silicon based cleaner on the tint works wonders. I had my tint basically ruined at a carwash using a windex type cleaner. It looked like they used steel wool on my tint. I got out the silicon based cleaner, It took a while but now look brand new. I guess it fills in scratches and bonds with the tint. The brand I use is called Solar Solutions. Hope all is well!! Later Scott
