Based on this, it sounds like using @ 99% confers neither advantage nor disadvantage - one just needs to use less than the volume of recommended 80%.

Time and time again, we come back to 80%.   I still find myself wondering if at some point in the past, this was simply the most commonly available concentration, which lead to the simplification of Bailey's original recommendation of =/>80%, to simply  =80%.

Based on responses, I see no reason *not* to use my 99%, undiluted - I can just use less of it.

Thank you to everyone who responded.
