My Mum is quite incontinent now and often forgets to put a pad on, or soaks it so much that she wets her pants and trousers. She'll take them off and change into 'clean' ones - the pants are usually clean, but then she'll put the trousers on the radiator to dry. Obviously, non-dementia Mum wouldn't have done this, but dementia mum doesn't seem to realise that this makes them smell. She'll do it time and time again. I don't live with her, so it's difficult to get her to put them in the wash - the only things she seems to wash these days are pants, nighties and handkerchiefs. Very, very rarely do her outer clothes get washed unless I happen to notice a stain, and get her to change then and there. She wears different clothes every day, as is her habit from working in an office all her life, but unfortunately seems to have forgotten that they need washing in between wearings! If your Mum hasn't got a UTI, perhaps this could be the reason that she smells smells strongly of urine.
