Antifreezed Carpet and Insulation

When I picked up my Barracuda, the heater core had leaked a considerable amount of antifreeze into the passenger floor-wells. When I got it home, I took the shop-vac to the carpet to pull out as much as I could until I had a chance to start yanking interior to clean up underneath, which I finally got to today.

The carpet and insulation don't feel soaked, but the pad is still damp.

I'm looking for opinions on whether this is a let the pad air dry for a while and it's fine, or scrap it and get new situation.

Eventually I want to Dynamat, so don't want to put a ton of $ into that at the moment, but if this is all going to act like fiberglass home insulation and basically never dry, then I need to do something now.

Thanks in advance!
