My lo ears is always very dry, may I know how u all keep your lo ears clean and what u use if your lo ears is very dry?

i dip the ear buds in mustard oil and use it to clear the outer and inner area, as well as add a few drops of the same in the ear canal (only after my kids turned 2 did i add to the ear canal). after some time i wipe all of it with a clean ear bud and the dirt just comes out very easily. i do this twice a week.
