Making the most out of our graphical telemetry computers.

Like with many complex instruments, there are multiple ways to solve certain problems and to measure the required inputs. Combining the various functions leads to a multitude of advanced uses.

Brass instrument care

Regular cleaning and maintenance (to prevent or remove tarnish)

After every use: A microfiber cloth dipped in hot soapy water removes dirt and dust buildup. A toothbrush can help clean out holes and engravings. After wiping down the metal with a soapy cloth, rinse the item and dry it thoroughly.

Weekly: Wiping the tools with a little liquid ammonia (a solution of ammonium hydroxide) on a soft cloth will help keep the surfaces shiny. The metals look brighter and require less polishing if rubbed with a cloth moistened with olive oil after each cleaning. The olive oil retards tarnish.


To polish, you can use special commercial polish or anything lightly acidic - lemon, vinegar, or even tomato juice work well. Clean with soap and water afterwards. Not polishing will protect the metal by keeping the tarnish as a barrier to further corrosion and wear.

Heavy stains and corrosion

To remove heavy or uneven tarnish:

  • Wash in hot, soapy water
  • or a weak ammonia and water solution.
  • Dip a slice of fresh lemon into table salt,
  • or make a paste of flour, salt and vinegar.

Rub into and over the corroded area and thoroughly rinse with water afterwards.
