Using Liquor on these type of dampeners was normal For a long time. Alcohol (isopropyl Liquor) was applied because it amplified the drinking water viscosity and created it "a lot more wettable" so that transfer was easier from just one roller to the other. However, Liquor substitutes which include glycol ethers, butyl cellusolve, and so on., are getting used currently to perform precisely the same undertaking mainly because Alcoholic beverages is made up of volatile organic and natural compounds.
