Hell, I always use my foot - if I bother at all....I be good at the high-kick thing.
Seriously, when we travel, I carry a small aerosol of germicide spray and hit all the hotel doorknobs, plumbing handles, phone, TV remote, bathtub bottom and A/C thermostat; then after a shower, I hit the feets with athlete foot spray.
2 most contaminated items in a hotel room are the phone and TV Remote.
Floors are a given.
Zip lock bag works good for the remote and for me the phone is too expensive to use.
