First thing is to remove the Cover by opening it to the vertical
position and lift straight up. Next lock the carrage and remove the
two screws exposed by removing the cover. Slide the top by applying
pressure toward the back of the unit. There you have it.

The best way to clean the glass is by using steam, if you don't have
steam try Windex with a lint free cloth.

Isopropyl alcohol works well too.

Also when you polish off rub one side at 90° to the other side. That
way it will be obvious which side of the glass any streak is on.

ummm... how do you apply the steam? hold it over a teakettle? or is there
some specialized glass-cleaning steamer?

Also, re isopropyl alcohol recommended elsewhere on the thread -- I've found
the drugstore variety can lead to streaking. A very pure variety can be
found at pro photography shops, one brand name is "Eclipse optic cleaning
system". Also, paper towels seem to be made with incredible amounts of
soluble goop .. the same photo store will sell you fancy lab grade "PecPad"
wipes. Or the lint free, carefully laundered and rinsed cloth.

The steam cleaner I am refering to is all of the Euro Steam cleaners as
seen on the TV shopping channels. I purchased one about 3 years ago
and realy love the way it cleans glass and my microwave oven. The
latest ones are cheeper and more compact and have more attachments.

The Steam cleaning method with an old t-shirt leaves no streaks as do
the other cleaners (alcohol/windex).

I remeber a few years ago, in an audio equipment magazine (Audio),
a retired chemist recommended vodka for cleaning tape heads. I wonder
if it could be used to clean the inside of the glass. As he said, you
know what you can do with the left over vodka.

Vodka is alcohol. It is one half alcohol and one half water. (100 proof)
You can buy at a liquor store 180 proof alcohol, one brand was EverClear.
Pure Alcohol is 200 proof.

You can buy at a drug store 91% Isopropyl Alcohol. Ordinary Rubbing Alcohol
is 50-70%. which means that it is mostly water.

By an odd coincidence, this morning's paper had a little tidbit (with
picture) of the Steam Penguin -- "electric steam cleaner ... clean windows,
glass, and tiles. 'I'llnever do windows the old way'" at
www.discountcellar.com, fwiw.

I really have to keep better informed on household cleaning trends :-).

I don't think it's the alcohol/water ratio that's really important for
streak-free cleaning, but the tiny fraction-of-a-percent impurities, like
hardness in water.
In chem lab, we used to do a final rinse or two with distilled water to get
really clean glassware. Come to think of it, that might be another
possibility (*distilled* H2O, not spring water, defintely not mineral water
:-).

Terry,

Thanks. I should have looked more closely before posting! I used
Servisol IPA 170 isopropyl alcohol 99% pure to remove the outgassing.

This is rather dangerous stuff very inflammable and toxic but perfect
for glass. One word of caution NEVER apply to a plastic lens as it will
destroy it.
