I’m sorry that you are having this stress. Sending extra-warm hugs. {{{alstroemeria}}}
In your place, I would use one of the super-absorbent products made for baby diapers. These are thin enough to hold to the Swiffer surface with large clamps. The contain synthetic polymers that are much more absorbent than cotton towels. (That’s why they are called “super-absorbent.”) Not cleanable…but millions of people use disposable diapers. This is assuming that you want a way to clean up your DH’s “accidents” because he doesn’t want to wear adult-size diapers.
