Great Piston Tuba Valve Brush

I was at Lowe's the other day in the paint roller section and came across a 2 pack of Microfiber Mini paint roller covers. These were a low lint variety. I believe the 2 pack was under $5 and then all I needed was a trip to the nearest Asian food restaurant for a set of chop sticks. Voila, insert the tapered end of one of the chop sticks into the paint roller cover and remove your valve, spring, and bottom cover and have at it. Works great, and you have a spare too!!

How about a similar hardware store coated cleaning snake solution??

Here you go, go to a pet shop and get some small white mice. Apply food at one end of the of the pipes of the horn and introduce the small white mice to the other. Eventually the mice will find the food source. Keep adding additional white mice until they come out "clean".

Don't you have to put little shoes on them first??

Else, I'd think they'd get no traction in there....
