Thanks for your query.
Read and understood your history of ear wax smelling bad.
The cause is the ceruminex and the sweat produced in the ear canal skin is different from that of the other areas of the body.
It looks that you are excessively cleaning the ears canals and allow the entry of the bacteria which produce gas and that gives the smell to the wax.
I would advise you to consult an ENT Surgeon to get yourself an ENT examination and decided the cause and treat if required.
I hope this answers your query.
