Hello Exd, this is something I have personal knowledge f and feel I can speak openly here. Incontinence is something I have had to live with since becoming disabled with MS.
I have always been fastidious in my personal hygiene habits and worried that other people may find I, or my home, may smell of urine.
But I am assured by family and carers that neither is the case. Before I found the solution to any possible unpleasant smells, I did find my bedroom carpet held a deep down smell, which regular cleaning products could not remove long term.
Urine can seep into a carpet and crystals form deep down, even after shampooing and the smell can return.
The only way to deal with this is to remove the carpet and have washable flooring like vinalay.
Next to pads......I am supplied with NHS ones...Hartman Products. They are bulky, but sitting in a wheelchair does hide their visibility. And if my supra pubic catheter should bypass, these pads hold a full bladder`s urine, without smell or leakage.
So this is the answer to smells with your daughter`s MIL.
BUT if she wont use them, it wont work.
