Drying out Live rock to use later

Lost my 125 gallon tank to a recent power outage from ice storm. Going to move when house sells. Would like to save rock.
1. How can I dry out the rock in the winter without smell in house (house on market)
2. Will storage in basement or garage produce a smell or unsafe gasses.
Once dry...I plan to store it in my garage in a tub. Temp outside is around the high 20s to high 30's
Would like to tear down tank tomorrow due to the eye sore of a dead tank and house on the market.
Could put rock in tub in kid play set with a fort in backyard
Suggestions please
