Prepping vehicle windows

I use a super fine (White) scotch pad with isopropanol diluted 50/50 with distilled water for cleaning. This has always worked in prep for applying tints or fly-eye vinyl

 

Bonami

 

This^^^ or Bar Keepers Friend. I sprinkle some on a damp cotton rag and scrub away.

 

I usually use alcohol, but helped a window tint shop redo a vision print job (their customer changed their mind on a couple images) a couple weeks ago. The decal (70/30 briteline) had only been on a less than 48 hours and the adhesive was completely adhered to the glass (usually it will "snap off" but we had to scrape it off). They had just used DirtOff with a window squeegee after razor blading the window. I'll probably try this again in the near future and see how well it holds up (especially on front windshields where the wipers might come in contact)

 

We’ve used the Magic Eraser or Soft Scrub

Of course try in a small area first to ensure it does not damage the glass

 

I use rapid remover, clean away, rapid tac, clean away. Over the years I have also decided that Newspaper is the best thing to clean windows with. Works better than microfiber or paper towels.

 

Uh...from their website FAQ section

 

I use acetone. It’s safe on glass, but keep it away from paint. Old trick I learned from my days as a professional photographer. Nothing will clean high end optics better. It gets rid of stuff like RainX on automotive glass quickly and easily.
