A didgeridoo does not need so much maintenance. On the outside, the didgeridoo is often painted or lacquered. A didgeridoo can withstand moisture just fine. However, you must put the didgeridoo upright after playing so that the moisture can run out. You can use beeswax to repair small cracks and holes in your didgeridoo. You can also use beeswax to put a mouthpiece on your didgeridoo. This is not difficult. Within 10 minutes you mount a mouthpiece of beeswax on your didgeridoo.
