@rauliruegas , The stylus does not go to the bottom of the groove. It does go deeper than the cloth is capable of drying because I have watched the water pile up behind the stylus. Anything you drag across the groove is going to pick up debris. I personally would rather that it was not my stylus doing the cleaning.
Do you know what Lyra Stylus Cleaner costs? $60 for a tiny little bottle. Shoot, Clearaudio sells a bottle twice the size for 1/2 the money and you still even get a brush.
I have a brand new high power photomicroscope coming!!! (Wallyscope) I will be able to take before and after pictures of styluses and nose hairs. This one is good enough to see stylus wear. I am going to make a designer record cleaning solution for machines with vacuum drying. I stumbled into an interesting discovery which needs more study. This could be my retirement gig:-)
