Vacuum the oboe case with a bristle attachment to initially remove any debris that may be left in the case.
Dust the inside of the case with a feather duster to ensure that no dust was left behind by the vacuum cleaner.
Wipe down the insides of the case with a slightly damp, but not wet, cloth. This removes any remaining debris.
Close the case after you've removed your oboe to play. Many oboists keep the case open during practice sessions. This is unnecessary and allows debris to enter the case.
Clean the oboe by using a cleaning rod and running it through the inside of the clarinet barrel. Wipe down the outside of the oboe after use with a dry cloth. This ensures the oboe is clean before placing it in the case.
Wrap the oboe in a cloth before putting it back in the case. This ensures that any debris left on the oboe won't fall into the case.
