Lorrie, I was catching up late last night, and read your post. I just wish I could help. I've dealt with this issue, only a little---an incontinent mother-in-law.
I woke up in the middle of the night determined to do something, if only a little.
If you would feel comfortable PM-ing me your address, I would like to send you a box of "stuff" to try.
One of the members here sent me a package when we were first dealing with catheters, and I really appreciated her help. I'd like to "pay it forward" and send you some disposable pads and a kind of room de-scenter that has helped us a little. If these work, they will be an additional weapon in your war against the cancer.
Have you tried a diaper pail with a soaking solution for the used pads before you send them out to be cleaned? And have you visited some of the ostomy sites for additional suggestions? And while we're talking about that, have you investigated a diaper service? They would return your linens smelling really clean, and maybe even provide a receptacle.
It sounds like you are doing the absolute best for him, and you are to be commended. And hugged!
