Vinegar can be helpful in neutralizing the alkalinity of urine on the skin, preventing the rash from spreading any further. Using a vinegar rinse to wash the baby’s bottom can help restore the skin’s pH balance in the area and provide relief from rash irritation.
To use, make a vinegar rinse with one teaspoon of white vinegar mixed into one cup of water and apply with a cotton ball or soft washcloth when changing baby’s diaper. You can also make the solution and store it in a spray bottle. Use this solution repeatedly at every diaper change and make sure to pat skin dry before putting on a new diaper.
For babies wearing reusable diapers, a vinegar solution can be used to wash or rinse diapers after each use. This can not only help to get rid of any urine smell from the diaper but also disinfect it at the same time.
