Oil in chins fur?!!

Hi, my chin Luna suffers from dry ears. I usually use the tiniest bit of olive oil and it works great and I’ve never had any problems with it before.

Last night I done my usual but she was tired so she want to sleep. Her ears go back when she sleeps and now it’s in her fur. I’ve given her a dust bath but it doesn’t seem to have helped too much. What do I do?
