How to Soften Hard Rubber | Hunker

As rubber ages, it hardens. This happens when the softening chemicals called "plasticizers" bleed out. The hardening process can take years, but it can be reversed before the rubber gets so brittle that it crumbles. Plasticizers keep rubber in a pliable state for better utility.

You can't, in general. As it ages, rubber loses the plasticizers that are incorporated into the chemical mix. Continued cross-linking sometimes also makes the rubber harder as it ages. This is the reverse of men BTW. You can soften rubber with different chemicals though. Naptha also works for some others, MEK.

Generally, natural rubber will revert (soften and lose properties like tensile strength) upon over-curing or heat aging, so, theoretically you could apply heat to the rubber and it'll soften somewhat, but the surface may get sticky from excessive reversion and the strength properties will go down (along with the desired hardness drop).
