[ATM] Mirror cleaning solutions

[artbianconi@blast.net]

My limited experience with this suggests that "hard" water creates an 
equally hard residue consistant with the calcification one often sees 
inside water pipes over time. I've seen steam irons turned to junk in 
six months with caked on white coatings in the reservoirs that could 
only be removed with an ice pick. 

The solution at the time was to defrost the freezer and capture the 
melted ice. OK for irons but I'm not sure I'd trust my mirror to that 
stuff.

As for vaseline soaked cotton swabs, they are one of the favorite 
devices carried by hikers. Stored in a metal tin, they are execellent 
for starting camp fires.

I tested this idea.  I smeared some vaseline on a microscope slide 
and then swabbed it with concentrated HNO3.    You are right!   The 
HNO3 did nothing to the vaseline, and neither did the tap water I 
rinsed with. 

So the cleaning process must require distilled de-ionized water.  I 
burned the cotton swab in the fireplace, and it was really cool how 
it flared up!  I bet you could make firecrackers outta that stuff.
