Lately I've noticed P's nighttime fitteds WREAK of ammonia in the mornings (ugh).

I've added an extra rinse cycle before washing with tide AND have added stripping them more often (don't smell when I pull them out) but they still smell after she wears them.

I read boiling dipes is one way but know that's not advised when you have elastic that could be damaged..... I'm going to try adding a couple tsp of tto to the wash today to see if that helps.

Any tried & true ways to get rid of it?
