The tint shop gave me a bottle of cleaner that's safe and apparently provides some sort of protection too. Smells like isopropyl alcohol to me. Don't use Windex or anything similar as has already been mentioned. It turns your tint purple.
ok i just got my windows done... 5% on the back and rear passenger doors... and 15 on the drivers and passenger windows... i love it... it's awesome and dark and sweet... only thing... i have a small thin long bubble in my rear window... so now i gotta take it back to the guy to get it fixed.... oh well
anything that doesn't contain ammonia. Such as Ammonia free windex, 20/20, invisaglass, any a few more... some say baby shampoo mixed with water in a spray bottle... I'll just stick with the store bought products.
