Mold is real bad news!

I have stored the leather seats to one of my cars in the house. The environment there is a little better than the garage. (not much). Keep the insides of the car clean. You can use a little Lysol in your cleaning materials to help things. Keep the air dry. Any adsorbment type is better than none. Check it regularly. Replace or dry out the adsorbment type material in the oven. If you have leather surfaces, use good cleaners. Lexol is one but there are others. Neatsfoot oil is a good leather conditioner. It will keep things flexable. Above all keep the leather clean.

The rewards of this effort will pay you back for a long time.

Good luck,
