Fluid
Isopropyl Alcohol is otherwise called rubbing alcohol. It
usually comes in less pure state, like 70% pure, for
around $1 a pint.
If you keep it a while, the moisture will get inside and
it will not be 99% ..
A little water will not hurt your lens, and other than
trying to find pure IPA, which would be availablke at a
chemistry supply, the
70% stuff will suffice and it is cheap.!
Try Clearsight as well for a more modern lens cleaning
solution..

Rubbing alcohol will work. The idea of the 99% stuff is
that its dry and evaporates quickly and without any residue.
Isopropyl comes in 70% (normal rubbing alcohol), 91%, and
99%. 91% is about what pure alcohol becomes on exposure to
air, it absorbs moisture up to this point and stops.
Supposedly the antiseptic properties are at a maxium at 70%
but I've also seen 91% quoted for this.
I have no idea what Clearsight is. Many proprietary
lens cleaners do not give the ingredients in the MSDS saying
only that they are non-hazardous and are proprietary. From
some other sources I've discovered that mostly they are just
plain alcohol or Ammonium carbonate or both. I've found the
Butyl alcohol cleaners superior to either plus they are
recommended for cleaning scanner windows, etc.
