Winter crud on inside of windshield

Anyone have suggestions for cleaning the inside of the windshield?

I have a thin film of "something" on the windshield from all the
winter driving with the heater air blowing on the windshield. ALmost
looks like what hyou get with a hole in the heat exchanger (had that
happen in the Chev Monza) but no puddles or lost coolant so it can't
be that.

Really bad when the sun's from ahead, so I have sun glare by itseld,
glare off of the streaks on the outside, and the glare from the film.

I seem to have terrible luck with Windex (in spite of all the hurting
crows from their commercials) -- lots of streaks and smears.

 

i have used some sort of "no fog" window treatment i
found at a automotive store...track auto, or one of the
chain stores...you might want to try some of it...i think
there are two or three products that adv to minimize
inside window foging.....it puts a thin film of treatment
on the window.....richard / colorado....

 

I find I can keep my windsheild clean with a wet chamois, wait for it to
dry, then polish the glass at night with a light aimed at the car
(streetlight, garage light... something that will show the streaks really
well)... Polish using a soft cotton cloth. I've had excellent results this
way, no chemicals just water.

Hello:

Windex is part of the issue as it contains waxes and is the worst
product one could use for cleaning glass.

Do what professional window washers do---use a solution of warm water
and Dawn dishwashing liquid, then squeegee or polish dry with a soft
lint free cloth.

Then, to prevent fogging take a large potato and cut it in half and
rub it on the inside of the windshield then polish after the moisture
dries.

I am not making this up or making a joke. I grew up in Northern NY,
Province of Ontario and Nova Scotia.

We had no commercially available anti fogging products and they old
timer I bought my 1964 Volvo Canadian told me about the potato trick.

I still use it today and it seems to work.

thats one i will have to try.....thanx....

 

A similar condition can occur on the outside of the windscreen. If one
uses the 'drive through' car washes, the spray rinse/wax builds up on the
glass, causing wiper chatter and other irritations.
I find a non abrasive scouring powder like Bon Ami or Ajax on a wet
windshield works well to remove the buildup.
Afterwards, clean as described in Doc's post and apply Rain-Ex to suit.
ymmv...

 

A cautionary note here. I used Rain-X on my wife's windshield (well, her
*car's* windshield) and a few weeks later washed it with that Mr. Clean car
wash that doesn't need to be towelled dry. Lazy, I know. Anyway, it rained
soon afterward and the windshield was covered with a dense white waxy
coating when the wipers went over it. We pulled into a gas station where a
lot of scrubbing got the windshield to the point we could see through it.
The coating cleared up when the rain stopped, but the only way I got it off
completely was with polish from a rock tumbling kit. The two products don't
play nicely together.

And I think Ajax is abrasive (silica) - it used to be, anyway. Bon Ami, Soft
Scrub and Barkeeper's Friend are okay.
