Main reason for this reply is that you posted your inquiry in an archived Schulze Forum . Archived forums are generally not used for receiving current /new posts or inquiries. It was sort of by accident that I found your recent post. There are possibly other people who might have good advice for you but won't know to give it if they also don't see it by accident.
There is a Schulze Forum that is intended for posting current/new posts.
By the way, on the question of using peroxide in the ear, it may have been me that wrote that advice you refer to .... not sure, many people use this advice, so I don't know if it was me that wrote the one you refer to. As a general rule, I stand behind that advice but also advise you to repost your concerns in the active Schulze Forum . Good luck.
