I stored my soap in the garage last summer. Problem is I live in Las Vegas and the garage gets really hot. My soap now doesnt smell too good. I could just keep it in the house but is there any benefit to keeping it in the fridge?
If it isn't rancidity, trying planing it. If you don't have a planer, trying running it under hot water for a few minutes (wearing gloves to prevent fingerprints). Sometimes that will "awaken" the original scent if it has faded or been stored too close to a strong scent and absorbed some of it's buddy fragrance.
