[BC] Tape deck issue/cleaning solutions

[Hal Schardin]

State Services used to purchase 8 oz. bottles of head cleaner for
about $7.00. I was able to get 16 oz. 99.9% isopropyl from a local
drug store for about $4.00 for 16 oz. The drug store was local; not
a big nationwide chain.
Since then, I've been buying gallon bottles of 99.9% isopropyl from
a physicians supply house for less than $12.00 per gallon.

Some of the electronic supply houses have 99.9% isopropyl alcohol. 
I
remember getting 99% at the drug store before, but, not now.

When I can find it, I buy the 91% isopropyl. The stuff is
definitely one
of 
the best electronics cleaning solvents for the buck! With only
about 9%
water, 
it evaporates *very* quickly and cleanly. That tiny film of water
(which
is 
pure) doesn't take long, either. Just a few seconds longer than
the
alcohol, 
with a little breeze blowing on it.

They used to sell 32oz bottles of it at Stop & Shop. Then they
stopped.
They 
also started putting "Sudafed" behind the counter. The whole thing
was a

mystery to me, until I found out that these are common ingredients
in
the 
manufature of "Meth". Good grief. Now you can't get original
"Sudafed"
anymore, they 
have something else. (I also heard that the original formula had
some
nasty 
side-effects, so this makes sense.) Still, finding the 91% alcohol
has
become a 
bit of a challenge. I've seen 12oz bottles at Walgreens, and
scarfed
them when I 
can find them. I use a spray bottle to get it down into the nooks
and 
crannies of circuit boards, and it really does a great job at
getting
the gunk out. 
It even works on oily residues, etc. (But man, does it stink!
Highly
flammable, 
too!)

I was able to resurrect my computer's printer by washing it with
hot
water, 
then giving it a good dose of 91% isopropyl. That displaced the
water
and 
rinsed away the rest of the gunk. I figured it this way: If this
makes
it worse, no 
loss, as the thing wasn't working too well. I would just be tossing
it 
anyway. If it fixes it, I've saved $89! Well, it worked great! The
thing
is like 
new, and yes, I was quite pleasantly surprised. :)

Ah, yes- another thing that isopropyl is *very* good at removing:
Pen
ink. 
Read: Graffiti. It also does a good job of removing "permanent"
magic
marker, 
too, and printer ink from your hands.
