What should a dishwasher do to make sure a sanitizer will work well?

A dishwasher,after washing, must dry his hands completely using a paper towel or hot air dryer, then he should turn off the faucet with paper towel.
Afterwards, he must apply an alcohol-based hand sanitizer because hand sanitizers work best on clean hands. So he must use the hand sanitizer after properly washing his hands, but not instead of just washing his hands.
The most common type of sanitizer employed in food institutions could be chlorine and water , an ordinarily used supply of chlorine is bleach.
