Grovia makes staydry boosters and inserts too if you want ones that fit perfectly. Or any fleece liner will work. But if it is not irritating your LO, I wouldn't worry about it. We have been marketed to by disposable diaper companies that baby can't feel wet ever, but for most babies it is really no problem, and can even help with potty learning.
I have used California Baby diaper wash spray, it is nice. I usually just use plain water in a spray bottle though, always have and still do for pees. Her poops are so yucky now though that I prefer to take her to the sink and wash her bottom with soap and lots of water.
