My best guess is it actually tar build-up from smokers (hey, fact of
life if someone around your car smokes, especially if you have the
defrosters on, which pumps the smoke fresh against the glass). Also
applies if you have any smoke-belching factories in the area or
Basic concepts: certain chemicals cut tar better than others, and
newsprint rubbed with significant force against glass will lift the
Old School Method: Newspaper with vinegar or 50% vinegar + 50%
rubbing alcohol. White vinegar preferred, and a 1.5 QT bottle costs
about $1.50 in our area. Spray vinegar on the windshield and scrub
diligently with crumpled newspaper, refold or swapping to new sheet
of newspaper regularly. Newsprint paper is courser than standard
paper towels and works really well (brown grocery-store bags come in
second, but still far ahead of brawny paper towels or equivalent).
Down-side is labor-intensive and vinegar smell. Windex also makes a
vinegar version of their glass cleaner that's especially good for
this particular purpose. Afterwards, you may need to still use a
windex-style product to remove any soy-bean oils the newsprint left
behind (by the newsprint fibers will remove the tar).
Field Expedient (BBQ) Method: BBQ-style wet-wipes containing any
citric acid (like lemon juice), followed by more paper to wipe it
away. Again, for some reason newsprint and brown grocery bags work
better than other things for their abrasion and ability to pull in
tar. As a cig smoker, I always pocket an extra half-dozen wet wipes
at BBQ places and toss them in the glove-box.
Key West Method: Skip the wet-wipe, use squeezed limes or lemons (or
pure lime/lemon juice) directly on the crumpled newspaper and scrub.
Rescrub with dry newspaper until shiny.
Last-straw/ Chemical Method: Clorox Clean-up spray. Cover the dash
with plastic or aluminum before using, because it won't be nice to
it. Spray directly onto the glass, rub as above, swapping newspapers
until really dry. Repeat if necessary to get 100% dry and remove all
the tar. After being squeeky-clean dry, use traditional windex to
clean the window again of any hazing or streaking.
Now if the "smokers" aren't smoking tobacco, but something the DEA
frowns upon, the layer is probably tar + resin, which is much much
more difficult to remove -- go directly to the Last-straw/ Chemical
Method and expect to have to repeat more than once. We use Clorox
Clean-up on all sorts of computer plastics and CRT monitors that are
getting resold to remove years of cig tar build-up quickly and
completely, and it works very very well. Note that "Formula 409"
doesn't work for crud by comparison (nor many of the other cleaning
products on the market) for this particular purpose.
What normally won't work well: Ammonia-based glass cleaners and paper
towels as first cleaning -- use only to post-clean any streaking
after the above methods have succeeded.
