Well, what's done is done - I hope it works out for you. I live in Florida and have times when the neck of my mando gets sticky due to the heat and perspiration. I usually carry a small wash cloth into which I have sprinkled talcum powder. When the neck starts to stick, I run the cloth along the neck and my hands and this usually staves off terminal neck stickiness. Once I am back at home, I take care to clean the instrument and usually change strings, too. Some instruments today have the back of the neck finished differently - I think they call it a French varnish, which reduces the stickiness. Happy picking. -btmp
