I searched the back history on this topic but did not see any posts on using Odor Prevention Sprays. Yes cologne would be OK but then you have the smell of cologne (may be bad or good). I see a product "Hollister m9 Odor Eliminator Spray" being advertised. Anyone try this or another odor eliminator spray that is neutral and works? Being under home care and babies listings I think it may be for this type of smell. Yes cost is always an issue, but for an overseas flight and wetting this could be good for the 1 or 2 times I would use it a year to spray into my disposable beneath my PUL plastic underpants.
