I have bought a whistle with ABS Plastic Head a Brass tuning slide and an aluminum body.
I will not mention the brand as this might give a negative impression.
It was second hand when I bought it, and of course, I sanitized and cleaned it before using it.
What I did was I soak into warm soapy water, put vinegar on the brass slide to make it shiny and rinse, then dry, then use.
After a week or 2, there is this pungent smell that is sour like a vinegar/cider that comes out of it.
So I wash it again without using the vinegar. After drying it smelled like apples, then after a day, it smelled sour again.
I was wondering if it is my breath or my saliva. I brush my teeth 3 times a day or depending on how many times i eat. I regularly wash with mouthwash so it will smell good.
I have an ABS plastic whistle and it i use it regularly with the SMELLY whistle but it did not smell the same way.
I have a brass whistle which I play the same way and regularly for practice, which does not smell the same way.
So I narrowed down the result, it is not the ABS, it is not the Brass....then it is the Aluminum.
I wash them separately and dried them separately. I practiced again, then store the body and the head separately....
After 2 days or so, the Aluminum smelled bad... so my suspect was right.
Please help me how to treat the odor issue.
