More specifically, the interior of it. I started seeing the filmy deposit from the plastic dash degradation on mine, so decided to clean it. Oh holy crap, what an adventure that was!

I tried two different formulations of Windex, an alchohol based windshield cleaner I got from the auto parts store, grease-cutting 409, a vinegar and water mix, straight vinegar, and even a solution of Dawn and hot water! Nothing would get rid of the streaky, rainbow-hued smears (horribly visible from the outside in direct sunlight) except, in the end, many blue shop towels and lots and LOTS of elbow grease!!

Anyone know, first of all, what the hell I was smearing from one end of the windshield to the other, and more importantly, a fool-proof method for removal? Nothing I had would cut it, so it is a chemical mystery to me. Any clues, anyone?

 

I dunno, I always use windex, nothing else works for me in the streaky residue dept. Also, I use lots of paper towels. Using rags or the blue shop rags always leaves a film, for me anyway. Here is what I do:

1. Windex and roll of paper towels.
2. Spray decent amount of windex on the inside of the window.
3. Wipe with a folded paper towel til almost dry
4. Buff dry with a fresh paper towel.
5. Buff one more time with a clean dry paper towel to remove any streaks possibly there.

I use a lot of towels but they are cheap. No other process I have tried works as well as what I describe above. Don't know why, just what works for me.


If you actually have a foreign substance on your glass, I think I would choose straight rubbing alcohol. Straight ammonia if the alcohol does not work. The next level of cleaning would be brake parts cleaner, but be careful with it. Prob would damage the dash and the fumes in the cab would be very strong.

 

I use windex and paper towels.
If there's something left behind, I don't see it.

 

The best stuff ive used on any glass is from Performance products inc. Foaming glass cleaner. The man who has been tinting all my glass for years put me on this. I have nothing but crystal clear glass,no streaks,use blue shop towels from walmart.there cheaper. must do in the shade. use it on all cars trucks and all glass on house.keep away from anything with ammonia.

 

blue shop towels have a lotion or something in them that leave a residue. Only use white paper towels with no designs printed on them.

 

John Deere Glass cleaner works great for me. spray 3 spots on take my micro fiber towel, clean, then wipe again then wipe one last time for good measure.

 

I dont know what ones you maybe using.but i never get streaks. and white paper towels leave lint.

 

Well, if the blue shop towels are the culprit, then that would make sense. Happened on two windshields, and they are the common denominator. I will definitely try just plain white paper towels - or coffee filters (no lint) - next time.

 

I would try that. All the shop towels we have are like that. It's not like a tissue with lotion but it for sure does have something in it that is bad for windows.

 

Just use a old newspaper. Try it one time.
Build up on the windsheild ? Rubbing alcohol and old newspaper
Bugs on the grill ? Fabric softener.

 

Microfiber towels leave no streaks. When you wash them, use no fabric softener in the washer or the dryer.

 

Dryer sheets. Its the only thing that will get love bugs off in Mississippi

 

I'll second the newspaper tip. I dont know why but it works.

 

Ditto on the newspaper - it works.

 

NO BRAKE CLEANER!!!!!!!!!!!!!!!!!!!!!I melted my fingerprints perminatly into some plastic gun grips once. They got changed. They make these windshield wonder things that hold special pads. Also folks used to use newspapers so it wouldnt streak.
