<< Rubbing alcohol may be isopropyl alcohol or ethyl alcohol - read the
90% or 91% isopropyl alcohol may be hard to FIND on the shelf but its not
hard to GET. If you don't see it on the shelf in your local drugstore, ask
the pharmacist. >>
Sorry - I didn't know of ethyl alcohol sold as "rubbing alcohol". In any
event, I'd still refrain from using even 90-91% isopropyl alcohol if not in
dire need -- you're still ADDING 9-10% water with that concentration.
BTW -- if you buy anhydrous isopropyl alcohol, keep the container closed --
it tends to take on water from the atmosphere, thereby lowering its' drying
capabilities and increasing the amount of water you're adding to your tank!!
