What is the best way to unstick a trombone tuning slide?

I recently picked up a used Bundy student model trombone. It is a simple slide trombone, but the tuning slide is stuck. I was wondering if there were any effective/safe ways to unstick the tuning slide without having to take it in to a shop for repair.

Spencer’s idea is valid but get penetrating oil from dad’s toolbox or the local hardware store. You’ll have to clean well when you’re done.

Your local repair shop has a tool for this purpose and if that tool works easily they may not even charge you to get it out as it would only take a couple seconds.

Trying to get it out yourself could cause damage to soldered joints or braces and just isn’t worth the risk. If the letting penetrating oil work overnight idea doesn’t work – it’s shop time.

If it’s seriously stuck in there – as would be with corrosion – the repair tech will desolder the joints and remove them, then he will knock the tubes that are stuck out using a mandrel and a hammer. Then he will strip the contacting surfaces, polish them up, and resolder all of those joints back together. Not your typical quick home repair.
