Welcome, @Petitcanard! Pull up a pew.
Still at my mum's with lots of cleaning and laundry going on today.
I've also started on her key stash. Much like the brillo pads, she has tended to 'store' them in pots around the place. I've now fitted command hooks in discreet places near each relevant lock and have put the pots away.
The new boxes for mementos are labelled up and in use and look great. I've also set up glass storage jars with all sorts of treats (nuts, sweets etc) which are easy to access and should stay fresher for longer. Similarly, a tissue box now has tissues in it, rather than just being an empty box which is in the way.
A charity has been to collect 'the pile'. They took way more than I expected: numerous electrical gadgets, ornaments, photo frames, games... I'd guess about 5 sacks worth. They couldn't take the furniture this time so I will have to re-book them for that.
A couple of houseplants are taking their chances outside. (They weren't doing well indoors.) Another 2 may also be on their way out.
There was a rubbish bin in the bathroom but (sorry MN) I've emptied and washed it and put it away. My mum can't deal with things like this easily and we definitely don't need another tripping hazard in there.
I've still got a double duvet to get rid of. Where I live, the animal charities take them, but they don't seem to want them here. Not sure what to do about that atm.
More cleaning, diy and key sorting still to do but we're definitely getting there.
