    You own some very nice instruments.

    I remember an article on the internet about disolving what I think was limescale / crystalised syliva on some woodwind mouthpieces, they tried vinegar, hydrogen peroxide and kettle cleaner.. after a while I think it was the vinegar, removed the most.

    I just wondered if the repair shops use a paticular chemical to disolve the above in order to free tuning slides on brass instruments?

    Thank you for your advice. I think when all else fails, repairmen might use a small application of brute force.
    I need to really move all of slides on regular basis to keep them useable.
    I hope that you are performing in some great places.
    Again, your advice is appreciated.

    I dont know if someone said this or not but

    I remember someone telling me to fill the horn with water then feeze it, then let it melt the expansion and compresion of the ice could loosen it up a bit. I dont know if this is safe on pro horns I only tryed it on my marching horn.

    A shop I was working in had one of these. The trouble is, when a main slide sticks, often it is just one tube (normally the upper in the leadpipe). You need to get more force on the upper slide than on the lower, otherwise the tuning slide will be totally distorted, one tube coming out more than the other. This is why previously stuck tuning slides often won't push home all the way on top and bottom. We have found that the best method is to use tuning slide pliers judiciously on each leg, and "walk" the slide out. Yes, this is in conjunction with penetrants and heat and time.

    Of course, you cannot use these pliers on student Yamaha horns due to their insane construction - they do not have soldered ferrules. I use their other weakness which is lack of rigidity, and twist the whole horn back and forth to release the slide tubes. But, more than any other models, I have had to unsolder the receiver tubes and shock heat treat them to release. Yamaha, at one point, recommended cutting the slide in half and releasing each leg separately; then supply a brand new tuning slide!

    I've had luck with PB Blaster but it would likely dissolve lacquer.
