Good Morning America had a story on Bacterial Spray. The claim was you never had to shower again and stayed minty fresh!! They tested it on several people and it seemed to work. So, if your loved one doesn't like to bath or sponge this might be a solution if the smells are getting the best of you.
Side note: After reading about the products, I recommended it to a friend with severe psoriasis. he's been using it for 2 weeks, and is not that impressed. It's good/interesting, but not a miracle product.
---- more to the original point here, getting an elderly, dementia patient into the actual shower is half the battle AND then through the entire process. .. All that said, I don't think this product is very valuable to those of us dealing with a smelly relative. :(. .. Just my opinion. (Obviously)
Google it!! LOL
The guy who invented it hasn't showered in 12 years.
I'd buy it if/when mom ever gets to that point.
