Can alcohol be used on a staph infection?

No. I assume you are talking about topical alcohol (rubbing alcohol) on top of the infection. Alcohol causes tissue damage, and hydrogen peroxide or betadine is a better cleansing agent for skin infections, followed by a topic antibiotic ointment. If it is a severe infection, you may need oral antibiotics (or even iv). See your doctor if the infection is worrying you.
Can be or should be? It sure can be, but it won't help much! :) topical alcohol won't do much for a cellulitis (which is bacterial infection under the skin), and a shot of whiskey probably won't help much either. Best to see your doctor for antibiotics.
