Hi
@Wicey
The hardest thing I've had to deal with in my dad's dementia is definitely the incontinence. My dad doesn't think he ever wets himself and makes up all sorts of reasons why the bed, his trousers, his chair, the carpet, his slippers....are wet. We've had spilt tea, juice, man with a watering can (in the house??!!) and a hose pipe...
I've found adult pull-ups have been a godsend. At first we started with pads but dad quickly moved past that stage. At first he knew he was having accidents but now, as his dementia has worsened, he has no idea.
He now gets his pull-ups on prescription so ask for an appointment for your mum with the continence nurse if you haven't already.
It's a battle to keep him and his house smelling fresh and clean.
I use Kylie-type pads over his sheet in bed and a waterproof (rubber backed towelling) mattress cover. The cheapest I found were on Amazon.
I also use stick-on disposable pads by Abrena from Incontinence Choice on top of the kylie to save washing. If dad wet the bed he would just take off the kylie so having the disposable pad saved an extra load of washing!
If you use the washable bed pads never use fabric conditioner or combined wash and conditioning powders or liquids or the pads won't work and the wee will just run off.
I've found that using a carpet cleaning machine (I have a bissell) and a pet carpet cleaner shampoo helps to remove the smell. So does shake'n'vac.
For laundry- if things are left to dry I soak them in disinfectant to loosen the smell before washing. I add Napisan to the wash but some fabrics still seem to hold on the the smell
