[Tfug] OT: Llatex/rubber solvents

[Bender]

Look up the material safety data sheet or manufacturer technical reference 
to determine what the "rubber"-ized  material and solvent is.

Search engine this to find options.

You might try heating the propeller with.a heat gun. Heat may melt or 
othewise disrupt the compound enough to allow manual removal. Use adequate 
ventilation.
