7. TUNING SLIDES
All brass instruments have tuning slides, which also need lubricating. If any of them are
difficult to move, remove them, wipe them clean and apply tuning slide grease. Work in and
out to distribute and remove any excess. If they are really stuck you may damage the tubing
trying to remove it, take it to your repairer who will have the correct tools to do this.
8. THE ANNUAL BATH
About twice a year the entire instrument should be given a bath. Washing up liquid can
damage the lacquer; instead use a capful of a mild disinfectant such as Milton fluid (NOT
toilet bleach!). Long and flexible brushes can be obtained from your music shop to clean the
longer or more awkward tubes. Dry the instrument with kitchen roll or non-fluffy cloth and
reassemble, lubricating all valves and slides as indicted above. Do not try to remove rotary
Fingerprints may be removed from the instrument with a clean soft cloth. If desired
lacquered instruments may be brought to a shine using silicon based furniture polish, but
great care must be taken not to get any polish on the moving parts. Silver-plated instruments
and keys can be polished with a silver cloth, which can be bought in most supermarkets. Do
not use liquid silver/brass cleaner (such as Brasso) as this is abrasive and may damage valves
Small dents in the instrument will not affect it, but larger dents will alter the instruments'
tuning. Your repairer can advise on this.
