How to eliminate the elderly smell (unsaturated aldehyde)

What can someone use to neutralize or remove "nonenal" (unsaturated aldehyde or oxidation of fatty acids)from the skin, which is what you smell when you go to a nursing home, for example. Research claims this smell is a bi-product of growing old, and is released through the pours of the skin of the elderly, or possible someone with candida. It piles onto the skin and doesn't come off with normal soap and water. They said there was a soap for the elderly but I can't find it and would rather try a natural method if there is one available. Any thought or suggestions? Thank you!
