Yikes! I'll have to go look. Nope, nothing on the bottle about
percentages. Just non-detergent household cleaning ammonia.

No, ethanol melts some plastic and is not the same (as you know) and
not necessarily as good a solvent for ink.

Better, in my experience.
The reason for the mix is my experience that isopropyl will only
dissolve about 90% of the dried ink. Ammonia gets 99.9% of it.
BTW, mixing it with more ammonia does not improve it's cleaning
ability, it just makes it harder on your lungs and skin.

carries Coralite brand and they are perfect.
