Does crushing aspirin and mixing with water and applying toear cartilage help clean it and heal it? the piercer at the tat shop recommended me this because i got infected.

Infected Piercing: If you have redness, swelling or drainage at the piercing site then you probably have an infection for which you should seek medical attention.

Not my rec: Aspirin does curb inflammation, but will not treat infection. I would put a triple antibiotic ointment there, and depending how bad it is, or if it doesn't get better, may need oral antibiotics. May take Ibuprofen or advil (ibuprofen) by mouth to help with inflammation. Crushing a non sterile pill intended for oral use and mixing with nonsterile water and applying to an open infected wound is not good.

NO: Actually this sounds like a good way to create an ulcer in your ear see a doctor.
