Great question Kabal
There are basically two reasons why household glass cleaners are not recommended for use on automotive windows. Firstly household cleaners have been known to contain ammonia. While this works great on mirrors and glass in the home, its not the greatest for car. Firstly, in the home you normally have open spaces which makes inhaling of the fumes a non issue, in the car esp. the interior it can be a bit of a concern. The other issue with ammonia is its negative impact on rubbers, vinyl and plastic. Not the stuff you want on your interior or exterior trim. This should be a greater concern if your windows are tinted.
Secondly, our vehicle glass is exposed to harsher conditions like bugs, exhaust fumes, oil, tar etc. So while household cleaners work on the glass at home, they can fall a bit short when used on your car. You will see this in the form of streaking, and the need for a bit more "elbow grease"
Personally I've tried a lot of tricks to get my glass sparkling. And I can say from experience, newspaper is a SCHLEP ! While it may clean, the problem with having fibres getting into every nook and cranny is a pain. You have to constantly use clean paper else it just disintegrates. Even then it requires a few passes to get into the "zone". Do yourself a favour, get a proper
glass microfiber. Microfiber already works great on glass, but the problem with normal terry microfiber is you still get lint. That just drives me NUTS! Glass microfiber have a silky smooth finish and ZERO lint. This alone makes a HUGE difference.
I use
Autolym Fast Glass and it works a treat for me. I hated doing windows as no matter how hard I tried, I always had streaking when I pulled out into the sun. With fast glass, its literally a tiny squirt, and wipe clean. ZERO streaks. Again less is more, so you probably use less than 10ml per wash. That roughly gives you about 50 washes. Breaking that down into rands and cents. R65 over 50 = R1.30 per wash OR R5.20 per MONTH. Hardly breaking the bank for that convenience. :inlove:
Again as I always say, if what you are using is working for YOU, then that all that matters :thumbs:
But if you have any of the issues that I've mentioned above, then give the Glass microfiber and Fast glass combo a try :=):
