White wine is not a substitute for alcohol sterilization.
Medical sterilizing alcohol is an alcohol solution with a concentration of 75% made by strict ratios, which consists only of water and alcohol. The concentration of alcohol penetration is very strong, can penetrate the bacterial surface, into the bacterial internal, so that the composition of the bacterial protein coagulation, resulting in bacterial inactivity.
White wine to degrees to indicate the alcohol concentration, degrees generally in the 50 degrees up and down, far less than the alcohol content, and the composition is more complex, usually contains polyols, higher alcohols, esters, organic acids and phenols, etc., the role of these components on the bacteria is more complex, but also has the role of promoting bacterial proliferation.
In short, disinfection should be standardized with medical alcohol or povidone-iodine, white wine can not achieve the disinfection effect.
