Hello. I have a question about wipes. I have been making my own wipes solution (Baby oil, baby wash and baby lotion) in a half-gallon jug and pouring some over my clen wipes in a wipes container. My problem is- sometimes they get kind of musty smelling after they have been there a day or two. I heard that there is some type of essential oil that can be added to the solution that might help. Any ideas and or places where I could buy some? Thanks!
