hello and welcome to HCM,
As you have keenly observed, since you have dermatitis
problems then you will surely have wax or even dermatitis like problem in the ear canal
. It is anyway a skin lined part of your body and is a one way street!
having mentioned all that let me assure you that ear can get cleaned by itself especially when we chew and swallow and you do not have to use ear buds or clean them if they are not causing any problem
However in case of any doubt it is imperative that you meet your ENT who examine your drums properly and also evaluate if you have hearing loss
