There are so many DIY'ers here that I thought this would be the best
place to ask this car Q?
On one of my vehicles (12 years old - parked outside all the time) the
windshield has what appear to be rain streak patterns running down all
over it. I've tried scrubbing with various window cleaners including
spray invisible glass, windex, zep, etc and although it appears clean
and clear when its done, from the inside (and especially when it rains
or damp) those marks are still there.
Short of replacing the glass or grinding it down (both unreasonable)
has anyone any suggestions as to what I can use to rid the surface of
Any/all suggestions appreciated.
And Happy New Year everyone.

This requires EXTREME care. Acetone will cut the film left by RainX and
other crud. It will also eat paint. I would try to clean the glass
with acetone on a white cloth. Keep going until the cloth remains
white. Then wash with the ammonia or alcohol mix.
Whenever you're doing any kind of windows, do the outside with vetical
strokes and the inside with horizontal strokes. This is so that when you
see streaks or whatever, you will know which side to spend the time
Not sure the surrounding rubber will srvive gasoline on it.
Back in the late 50's, I've seen service station attendants [yes, they did
exist once] use a bottle of coke. Just poured it on the windshield then
washed normally. They swore it took off all the old road 'scuz'.
I just use Walmart Window Cleaner. Very cheap. That's stuff's good for
removing latex paint, too.
Those things are disgusting! We drove to Destin for a week, in
September. The car was caked in those things, by the time we got
there. We're told that they do a lot of damage to the paint if
they're not cleaned off immediately, too. Wife was not happy with
them coating her new convertible.
At Vicksburg, the Texans manned the line that looked like it was less than
60 feet to the yankees [can't imagine what it was like to be able to
recognize a cousin across from you!] and saved the day when the yankees
broke the line somewhere else, they just stepped in, or is that waded in?,
and held the line saving the day, well for awhile anyway. I think along
with Tennesee people, but can't remember now.
Now you see why when we do cross-country trips; we ALWAYS rent an
unlimited mileage car. You should have seen the windshield after the
sandstorm near Reno. Or, the damage due to the construction truck carrying
a load of something and having it blow off onto us at 75 mph. Or, after
driving at evening time through Georgia, NC, etc and as your wife noticed,
the paint damage all over the front of the rental's very nice car! Both
from impact AND from little splattered body chemicals, whatever that
caustic stuff is!
For example, rented Cadillac from Hertz and put 16,000+ miles on it during
one summer's drive. Very comfortable car, but wouldn't want to own that
specific car after that trip! Needed a new paint job. ...and windshield.
What did Hertz say? Normal wear and tear, bless their hearts.
Same here. I've found Rain-X helps reduce the glare effect from
scratches and pits on windshields, as if it fills them in and smooths
the windshield out a little bit.
As for cleaning the windshield, be aware that the inside of the
windshield will gradually accumulate a greasy film, and the exterior
will often get streaks of mineral deposits from dirt/dust/mud and
dirty rain. Standard window cleaning solutions don't do very well
against the greasy film and mineral deposits. It's more helpful to
periodically clean inside and out with a strong detergent or
detergent/ammonia solution, rinse very well, then carefully dry. Lay
the wet washrag on the exterior windshield for a minutes before
scrubbing, to help soften the dirt so it'll wash off with less effort.
Sure, but vinegar doesn't work nearly as well as commercial cleaning
products. Vinegar is quite good at disinfecting, but not cleaning:
"The results indicate that compared to commercial cleaners, the
alternative cleaners as a group are less effective in both microbial
reduction and soil removal.
However, the alternatives vary in their effectiveness. Two alternative
cleaners - borax and ammonia - were more effective in soil removal
than the other altemative cleaners. However, borax was not at all
effective in reducing microbial contamination. Vinegar was more
effective in reducing microbial contamination than the other
alternative cleaners but was least effective in removing soil."
They used to be steam pressed, rendering thmm sanitized, so you could wrap
food in them, oruse them for birth/deliveries.
Now even the inks come out, cause smudging all over and absorb into your
system while reading, and reportedly change personality of those reading
It might interest some of you to know that greasy film is due to
outgassing of the preservatives in the plastics used in the dashboard.
Newer cars are the worst offenders and by time the plastic stops all
outgassing, that's when cracks sometimes appear in the dashboard. And
we wonder why the incidence of cancers keeps increasing.
Breath deep the gathering doom.... (apologies to The Moody Blues ;)
