I’ve been using fractionated coconut oil, lavender, tea tree, lemongrass essential oils. (DoTerra online) I modified my recipe as I use to add more other oils. Not necessary.
Shake well n seriously, very well, add to an unscented baby wipe n clean.
Been doing this for over 7yrs with Nyala’s tail pocket.
Was amputation or oils. I opt for oils. Never had issues.
My girls don’t have tail pockets but because of the war their tails lay, sometimes it gets a little yucky/yeasty underneath so when that happens I use Helene’s EO recipe above.
