I am reconditioning my old T-Bird (I own an F-150 but it runs great) and since it has to be outside all the time summer and winter, the interior gets mildewy. I periodically spray (coat) the inside with a can of Lysol and wipe it down the best I can but its a losing battle, plus I put a plastic tub of those water leaching crystals on the front and back floor but fear I'm just taking moisture out of the air outside even with the windows tight up. What inexpensive device or method can I buy to keep it dry in there short of an expensive dehumidifier???? Thanks for your thoughts in advance.
