Glass cleaning tips:

* Don't use household window cleaners, as said above if they have ammonia it ruins the tint. The manority are now all l ammonia-free anyway but it's still not ideal for auto glass.

* Only do the glass when the car is in the shade or cool to touch, if it's too warm the cleaner will just evaporate too quick & won't actually clean the glass.

* Use a clean cloth, old cut up towel is fine, fold into quarters & use a new side each window.

* Don't stress if it streaks, do a few windows then get a clean microfibre cloth, fold into quarters & buff the window. Streaks will disappear. If it's a warmer day you may have to buff them sooner than if it's a cooler day. Leaving them too long makes the streaks hard to remove.

* Get some plastic razors from Woolies etc, near the batteries, lubricate the window with the cleaner & run the razor over the glass to remove contaminants before cleaning.
