Is there mold in my tenor saxophone, and how can I get rid of the mold?

Can you reach the mould with a tooth brush? If so, work two tablespoons of bi-carbonate soda into a paste with a little water. Rub the paste over the affected area, then add one tablespoon of white vinegar. Sluice the liquid all over the mouldy area. You may need to add more vinegar. Wipe well with an old pair of nylons. Rinse out with hot water. Dry. Rub the entire area with "Oil of Cloves". This is a natural mould inhibitor.
