The advice, the whole advice and nothing but the advice

Confused of Scarborough has written to the Guardian today:

Your advice on Mask Hygene is of only moderate help. If our face masks, of whatever variety are to be treated with the same level of suspicion as we have for rats, where does that leave our clothes? Why doesn't anybody tell us to wash our clothes after every shopping trip?Would that be a step too far? And for the hirsute, like myself, why aren't we being told to shave our beards off, since we can't get a tight fit like the clean shaven? Perhaps one of your correspondents could provide some advice on that one.
