Anyone can tell me how u dig baby ears and nose?

I used the korean brand, B&B cotton buds to dig the nose. One end of the cotton buds came in spiral design so easier to dig the dirt out. I only clean the external part of the ear as PD said the dirt will fall out by itself since babies' ear canal is short. For the external area, i wet the normal end of the cotton bud and clean it. Everytime i visit PD, will ask her to check the internal to ensure it's not blocked.
