I bought a hospital bed mattress so I could Bleach it!!!I have cut drinks after 4p.m. to about 1/3 of a glass every time he has a drink!!No more FULL glasses!!Same amount of drinks but,NO full ones!!It did help !!😇😇😇

Maybe use a bed pad on his bed and a plastic runner beside his bed at night!?

White vinegar put into a spray bottle and sprayed onto the affected area will neutralise the smell of urine and vomit. The vinegar smell goes away after a while

There is some medication the doctor might be able to prescribe. Also, he could have Prostate problems that need to be evaluated. I would have him see his Primary Care Provider to be sure there isn't something else that can help.

Large absorbent pads are available at most stores. I believe they are 30x30, if you double them they absorb very well. I had the problem with my wife. They really reduced the need to do laundry every day. Walgreens brand named Certainty. Hope this helps.
