We hope you enjoy your newly hired instrument. Please take the time to read the following guidance in order to keep the instrument in its best condition.

Caring for your instrument

After Each Use

  • Use a ‘lacquer finish polishing cloth’ or a household duster to wipe off fingermarks.
  • Do not use any type of cleaning solution and do not use any harsh or abrasive cleaning materials as this may damage the finish.
  • Remove the mouthpiece and put it in the appropriate compartment to avoid it damaging the instrument during transit.
  • Should you find the mouthpiece is stuck, do not attempt to force it apart.
  • Take it to your teacher who will have a special tool to remove it easily.

Periodic Maintenance

  • General cleaning
    • Once every few months, the instrument should be cleaned internally, by running warm soapy water through it (hold the valves down whilst pouring water into the bell).
    • Rinse thoroughly with cold water and then allow to dry.
    • Do not use hot water as this may affect the lacquer.
  • Pistons
    • To clean the pistons, unscrew top and bottom valve caps and carefully remove each piston, noting to which valve they belong.
    • Clean using warm soapy water and brush, then use a dry cloth to make sure that no moisture remains in the valve casing, or on the pistons or related components.
    • If the valve is stuck do not forcefully remove it as you may damage the instrument.
    • Contact Essex Music Service who may be able to recommend a local repairer to look at the instrument.
  • Slides and Tubing
    • You can use a flexible cleaning brush to thoroughly clean out the slides and tubing.
    • Use the brush carefully and replace it regularly to avoid the possibility of it breaking whilst inside the instrument.
    • Unless you clean the inside of your instrument, a coating of saliva and dirt will form which will greatly interfere with its playing qualities.
    • If it is not cleaned for long periods corrosion of the brass can occur.
  • Mouthpiece
    • Always clean the mouthpiece thoroughly with warm water and a mouthpiece brush.
    • An accumulation of deposits in either mouthpiece or mouthpipe can have a very adverse effect on the performance of the instrument.
    • Once cleaned, gently place the mouthpiece back into the receiver and twist lightly to seat it properly.
    • Do not force the mouthpiece by hitting it with the palm of your hand as this can cause the mouthpiece to become stuck or ‘frozen’.
    • An easy twisting motion is all that is needed to ensure a firm fit.


  • Before reassembly, always lubricate the various parts.
  • Clean valves never stick – lubricate them with a good quality valve oil.
  • Apply several drops of valve oil to the top of the piston.
  • Return the piston to the casing, gently rotating it while turning it up and down, to ensure that the oil covers the entire surface area.
  • Turn the piston until the guide clicks into its slot. Refit and tighten top and bottom valve caps, remembering to lightly grease the screw threads first.
  • Follow the same procedure with each valve, but be sure to replace them in the proper order!
  • On most instruments the valves are clearly numbered 1, 2, and 3, but if they are not replaced in the proper order, the instrument will be impossible to play!
  • To grease the slides, apply a small amount of good quality slide cream to the inside slide, then refit to the outside slide and vigorously move it back and forth to spread the cream over the entire slide surface.
  • A drop of valve oil can also keep the water key spring and cork lubricated.


  • Do not eat immediately before playing, or drink anything containing an acid such as lemon or lime, as this is likely to create problems such as sticking valves, etc.
  • After playing your instrument remember to loosen the valve caps by half a turn to avoid the possibility of trapped moisture causing corrosion of the screw threads.
  • Try to avoid dramatic changes of temperature and humidity and never leave the instrument in direct sunlight or near a radiator (even when it is inside the case).
  • When using a mute, set it carefully so as not to dent the bell of the instrument.
  • Valve oil, cleaning brushes, and complete cleaning kits are available from local music shops.


  • The hirer is responsible for any loss or damage to the instrument and as a result we recommend taking out insurance.
  • You may be able to insure the instrument under your household policy, alternatively there are many companies specialising in musical instrument insurance.

Damage and Repairs

  • In the unfortunate event that your instrument is damaged, Essex Music Service should be consulted to seek approval and advice before any repairs are undertaken.

Essex Music Service provides quality music tuition and ensembles to schools and colleges throughout Essex, covering all major orchestral and band instruments and musical styles. Playing or singing together with other people (ensemble) is one of the most exciting and enjoyable musical experiences. We provide a whole range of opportunities for young people of all ages and abilities, covering almost all instruments and voice. Many of our groups offer students the chance to tour in the UK and abroad!

If you’ve never played or sung in a group before, one of our workshops would be a great way to get started. In collaboration with our partners, we offer regular workshops in singing , jazz , strings, wind, brass, guitar, percussion and rock – sign up to our newsletter mailing list to receive details.

If you’re a bit more experienced you could join one of our groups that meet regularly, either monthly or in the school holidays.
