I recently read, on another forum site, that a 50:1 mixture of water to wintergreen oil, heated to just below boiling, will 'restore' old rubber (carburetor boots, etc.) to "like new". Another inmate there opined that a mixture wintergreen oil and toluene will accomplish the same thing. Is this really the way to "restore" rubber or are the chemicals basically breaking down the rubber and the interim state is simply close to the way the rubber was when new? I'm more curious that anything. TIA.
