i tried using glass cleaner liquid, and for scrapper, i use the normal pen knife, then one you use for cutting lines on paper.... to scrap it, would work if you have dirty stains on the window but the rainbow strips cannot go off.. I have no idea but many told me that this is cause by excessive use of those liquid like RainX and bla bla.. not RainX brand la.. but some other lousy brand..

Well, I'm no expert, but I think it's when the laminate starts to warp from the sun. Polarised light will make the inconsistant tension across the film appear as rainbow colors.

So, it's not something you can wash. Need to replace the tint/laminate. I guess this is the difference between cheap tinting and $2000 tinting. :p

Autosol is a product where most clocks/watches shop use them. It is very effective to remove scratches of the watch glass screen.

Doesn't matter which to go for, all are the same. As long it is similar to the shape of a toothpaste, there is also another Autosol product but with different packaging. So, please check or read before you buy. :p

I heard from a friend work in chemical field said it's not the "dirt" (hope i can correct about what you guys refer to)....

he said it's the material that use to make glass is not "clean" when in the factory...

 

[edgar_raphael]

fritz is rite, if u use the polarized sunglasses the rainbow effect is much clearer. the rainbow effect ha, dont know how to explain but it is there due to chemical effect.

its the way they bend the glass while manufacturing it laa...cannot clean wan..its reflection from the sun..if u dun have tints,the more obvious it is

 

[fritz]
