How do I clean a pBuzz?

To clean the external red surfaces, use a soft cloth with warm soapy water and dry the instrument with a lint free cloth. We recommend that you clean the instrument before first use, being careful not to get soapy water on the clear tube as this may damage the coloured paper insert. We do not recommend placing or immersing the pBuzz fully in water as this can damage the coloured-paper insert sleeve inside the clear plastic tube.
