CARING FOR YOUR
ZHUMELL BRASS TELESCOPE
CLEANING AND MAINTENANCE
A telescope is carefully aligned during construction, and great care
should be taken to maintain this alignment over the life of the telescope.
Cleaning should be done as little as possible and then only with mild
soap solution and a soft, lint-free cloth. Do not rub elements when
cleaning. Blot optical components gently and allow telescope to air dry.
Store your telescope in its box or in a telescope case when not in use.
Do not use pure alcohol or solvents to clean any parts of the telescope.
Do not remove optical elements from the telescope as doing so may
affect the alignment of optical components when reassembled.
If telescope needs realignment, contact Zhumell or another professional.
• Brush telescope optics with camel-hair brush or blow off dust with
an ear syringe (can be purchased at any pharmacy). Do not use a
commercial photographic lens cleaner.
• Remove organic materials (e.g. fingerprints) with short gentle
strokes using soft white tissue paper and a solution of three parts
distilled water and one part isopropyl alcohol. You may also add
one drop of biodegradable dish soap to one pint of the homemade
solution. Do not use lotioned or scented tissues as they could
damage the optics of your telescope.
• Wipe down the outside of your telescope with a dry cloth to remove
condensation prior to packing up your telescope. Do not wipe any
of the optical surfaces. Instead, allow the optics to dry naturally in
warm indoor air prior to packing up your telescope.
• Protect your telescope from excessive heat. For example do not
store your telescope in a sealed car on a warm day. Excessive
storage temperatures can damage your telescope.
