Latex's Sulfur to Silicon Cross Contamination

Brian Le

If I make contact with latex on my armature head core, can the sulfur from the latex cross contaminate if I decide I will eventually work with silicon? Will I be able to clean the armature head core to make sure no sulfur stays on the armature head core? Could I use some kind of plastic food cover like Saran wrap to protect the armature head core from sulfur? Will the food wrap be difficult to separate from the latex if I'm doing something like this?
