Should I send my horn in to be cleaned?
I’ve had my horn for around four or five years and never cleaned the rotors. It belongs to the school I go to and is ridiculously old, likely thirty or forty years old. I’m not going to take the rotors out but I used my phone camera to take pictures down the slides. This is what I found and I’m mildly disgusted, knowing they’re not supposed to be this color. Is this so far gone that a good bath wouldn’t fix it? Does it need deep cleaned by a professional?
