Candy vs Instruments: What to Know

It's Halloween week! We know this means your students are likely hyped up on candy and bouncing off the walls, and teachers are dealing with the aftermath. With all this sugar consumption, we thought it was the perfect time to share some important information with your students about how candy and sugar can affect their musical instruments. Please feel free to pass this along and good luck this week.

Attention Students... Sugar is BAD for your instrument! Sugar from candy and other food damages musical instruments by leaving a sticky residue that traps debris, corrodes metal, and promotes harmful mold and bacteria growth. This sticky grime can affect all instrument types, but it is especially detrimental to wind instruments, which blow moist air directly through the internal components.

How candy damages brass instruments

Corrosion: Acids and sugars from food and candy can accelerate a type of corrosion known as "red rot" in brass instruments like trumpets and trombones. This irreversible process occurs when the zinc is leached out of the brass, leaving behind weak, reddish copper.
Sticky valves and slides: The sticky sugar residue can get inside the valves and slides, causing them to move sluggishly or get completely stuck. A valve that is slow or stuck will impede your playing.
Trapped germs: The warm, moist environment inside a brass instrument is an ideal breeding ground for bacteria and mold. Food particles and sugar accelerate this growth, making the inside of the instrument unsanitary.

How candy damages woodwind instruments

Sticky pads: The pads on woodwind instruments like the clarinet, saxophone, and flute are especially vulnerable. Sugar residue can make the pads and tone holes sticky, causing keys to stick down and ruining the instrument's seal.
Clogged keys: On woodwinds, candy particles can get lodged in the delicate keywork. This can cause keys to stop working correctly or even to bend out of alignment.
Damaged reeds and mouthpieces: Sugar can coat the inside of mouthpieces and damage delicate wooden reeds, affecting the instrument's tone and playability.
Blocked airways: In a recorder or other similar wind instrument, sugar and other food debris can block the narrow airway, which affects the instrument's tone and pitch.

Prevention and solutions

Avoid eating and drinking: Do not eat, chew gum, or drink sugary beverages immediately before or while playing your instrument. The only exception is water.
Brush your teeth: Brushing your teeth or at least rinsing your mouth with water before playing will remove food particles and sugar before they have a chance to enter your instrument.
Clean your instrument regularly: Swabbing out woodwind instruments after every use can help prevent residue buildup. Brass instruments should be given a thorough cleaning with a brush and soap periodically.
Consult a professional: If you suspect you have a candy-related problem, take your instrument to Palen Music for the professionals to repair the instrument. They have the specialized tools and chemicals to clean and repair the damage properly.
Most importantly: Listen to your director, respect your instrument and don’t eat candy before or while playing your instruments!
