Swarfega is a friend of Frost. And indeed any health conscious citizen. Wash your hands after using the toilet and most wind instruments. Up to and including Bassoons.
Remember, cleanliness is next to Godfreyness.
Evocative smell, too. Swarfega, that is, not Godfreyness.
Mind you...
Although after parping a Flumpet, bleach is usually recommended. If that doesn't work, amputation is the next best thing.
