Must admit I've not considered treating rubber speaker surrounds. But since I'm restoring a pair of classic A-25s for the den maybe I should.
I have used a treatment called Rubber Renue by MG Chemicals on rubber belts for turntables, CD drawers, and tape decks and that seems to be beneficial. I feel safe with that since it is formulated for rubber applications.
