Well, it was about 11 hours in the pouch. To my surprise this LP is unchanged. This is in stark contrast to every other LP I've tried thus far. Obviously vinyl from different sources may vary in chemical composition. Anyone else tried this on an older Mofi? Maybe they're more refractory to intervention. It certainly is no worse than before with the same beautiful sheen. If worse comes to worse I can just keep this one for side two.
At any rate, the risk involved in experimenting with this thing seems to be quite small. I do think I'll try the oven trick suggested by Miner42 but I'll need to pick up a couple thermometers first to make sure the temperature in my oven is accurate.
