Dear User, I am not an expert on sterilization, however here are my 2 cents: 1) 70% ethanol will cause less "glassification" of the contaminant particles and will be more likely to penetrate deeper, resulting in better quality of treatment. 2) 70% ethanol is better on human skin. 3) 70% ethanol is somewhat cheaper to make and to maintain -- 100% ethanol is extremely hygroscopic. Sincerely, A.G.E.
