Nicotine reidue on drivers


Is there a safe and effective way to get old nicotine residue
 off speaker drivers? Yamaha NS 1000m, I can see it on the tops of the tweeter and mid-range drivers.

91% isopropanol will not harm beryllium. Will it remove dried-on nicotine? Next to try could be acetone - again, not harmful.
