I've actually heard just the opposite about Borax, that it is harsh and can cause irritation to babies. I've also read that it can shorten the life of some diapers. We've been cloth diapering for 8 1/2yrs, and I've had the best luck keeping the wash routine very simple. A cold rinse with nothing, a hot wash with a tiny bit of regular detergent, and an extra cold rinse. I don't use baking soda, vinegar, washing soda, borax or essential oils, although I've used all at some point in the past. I've just found that they're simply not necessary on a regular basis, and if anything end up causing trouble after extended use. They might have an occasional use, once in a while, but for our normal wash routine with our soft city water, simple detergent and hot water is sufficient and doesn't give my dd any rashes.
