I have not seen it mentioned here yet, read it online somewhere for baby rashes and i had some and tried it, works very well...
Mix one cup of water with 8 drops of Tea Tree Oil (measurements are guidelines only, not exact).
I put this into a squeeze bottle and leave it where you clean up at. When you go to change, simply wet your wash cloth with this solution and clean your diaper area thoroughly.
Using Tea Tree Oil in a wipe solution is great because it is naturally antiseptic and leaves you fresh. An added bonus is the money you will save. The oil plus the cost of wash cloths is nothing compared to the $4 per package you would spend every few weeks on disposable wipes. In addition, disposable wipes are more likely to cause a reaction on your skin.
May be something someone else besides me has and wants to try it. I did up a 500 ml bottle, and converted to get the right amount of oil, and it is still over half full 4 months later. You don't need much on a pre-moistened cloth.
