I don’t quarantine anything. I wash my hands well when I come in from shopping, put the shopping away, I don’t disinfect or wipe it, then wash my hands well again.
Post is opened when it arrives, then hands washed well again.
Hands washed thoroughly before touching any food to eat or cook, veg peeled, fruit washed before eating.
I do my usual cleaning of bathroom, kitchen, work surfaces etc.
I don’t change my clothes, wash my hair or shower when I come in from shopping.
I’m fortunate to live in a quiet area, not crowds of people, not very busy shops, don’t have to use public transport.
