As long as you only put in whole peppercorns (without additional pepper dust), the disc will hardly get dirty from the inside. If necessary, you can vacuum out the residue with a hoover or clean it with a slightly damp cloth. I would not disassemble it. We have been using this pepper mill almost daily for a few years and are very satisfied with it.

I can't take it apart, but I have already rinsed it out with water a few times. So far everything is fine.

I've also been wondering how to do this. First I knock out the salt and clean with a dry cloth.

I got rid of the fucking thing a long time ago.

is quite a hassle to clean because I haven't figured out how to take it apart.
