I don't think you can guarantee to stop it from happening again. Paxolin is what it is....SRBP Synthetic Resin Bonded Paper so it is subject to moisture absorption (over a very long period though) and insulation breakdown.
Having scraped away the carbon perhaps try sealing it with a small blob of Araldite or similar Epoxy.
