Sticky helmet?

De-solve it is good stuff and organic based. Any solvent recommendation above will fuck it.

Unless it is just old fashioned mold (eeekkkk) I'd be inclined to bin the fucker.

It's not sperm coating it is it? Maybe a seriously fucked-up night on the hard stuff and one of the weirdest sexual experiences you have had?

If so - it's OK - these things can happen.

new helmet, what price do you put on your head? Failing that, Eucalyptus oil. As a bonus it'll remove any blockages in your nose

Since the shell is showing signs of improper storage, the inside is probably also deteriorated. Remove the linings and check because if there's any damage to the inside foam the helmet needs to be scrapped.
