I don’t do it. I sanitize my hands and wear a mask, that’s about it. I don’t wear my shoes indoors so I don’t worry about my shoes.
But if I hear anyone around me cough I literally run away even though I wear a mask. If I’m in a store I will drop everything and leave. Luckily in the 6 months of this pandemic I’ve only heard people cough 2-3 times.
This is basically my routine, if I've been out and touching things other people are likely touching then I get in, take my shoes off and go straight to bathroom and wash my hands.
Then live my life as normal.
When I get groceries delivered I wipe the stuff down I can with some wipes before putting them in fridge or cupboard.
I don't think you need to do much more than that. Mainly you want to avoid being in doors close to other people.
In most places except Florida, Texas and California, the probability of running into someone with covid-19 is low. Unless someone coughs in the vicinity around you, the probability of getting it is even lower.
If you’re really concerned, sanitize your hands and phone when you come into the house with hand sanitizer. Leave a bottle outside if you want.
Then take off all your clothes and put it in the dryer. The dryer at 70C is hot enough to kill the virus to undetectable levels in less than 5 mins.
You don’t need to take a shower, just sanitize your hands. If you’re concerned about your hair, wear a baseball cap and put that in the dryer with the rest of your clothes.
