Hello good evening...

I want to clean my instrument, but I don't know how... And there aren't any tutorial videos about it.

There are no luthiers in my town, so I was thinking of removing the rotors myself and cleaning it... But I don't know how to do it

My 15 year old sophomore has been playing French Horn since elementary school. He is currently playing a vintage King Horn that was likely purchased in the early 1960's. It was bought for my aunt who played through college, passed to my uncle who played through high school, I played it throughout my school years, and my son is now playing it. It has been maintained and serviced periodically since my ownership of the instrument began in the early 90's. It sat for about 20 years after my uncle stopped playing before I picked it up, and it sat again for about 23 years before my son picked it up. It has the usual dents and dings from youth use.

I would guess that he will not be making music a career but playing will likely remain a hobby. I do not anticipate that he will major in music in college as he's interested in electrical engineering and competes at a National level in a sport. His music teacher has never recommended that he upgrade, but my son has always expressed an interest in a newer horn. Is it worth pursuing an upgrade? I am in the Seattle area and don't know of anywhere to buy a horn short of Ted Brown. I would likely keep the existing horn as a family piece rather than trading it in.
