Wash your hands as best you can, for at least 20 seconds, with soap. Always take a mini bottle of disinfectant hand gel with you when you travel. Wet wipes are also very handy to have on hand. Next, wash hands with soap. Drying hands is at least as important for good hygiene on holiday.
Use a cotton roll towel dispenser
We prefer to dry our hands by using a towel dispenser with cotton. And that's a good thing. With a cotton towel (or paper) you remove almost 3x as many bacteria than when you dry them with hot air. Additionally, you prevent further spread in the immediate vicinity.
In Italy you will find many old air dryers to dry your hands. Fortunately, you see more and more dispensers and vending machines with a sensor for contactless use in restaurants. Especially in Poland and Slovenia, because they love innovations there.
