My uncle told me to put a box of baking soda in my garage to keep the Bel Air dry, and 2 winters in I owe him an apology

Back when I parked my 66 Bel Air in my unheated garage in Duluth, my uncle (who kept a 55 Chevy for 30 years) swore the fix for damp air was just a box of baking soda on the shelf. I thought that was boomer nonsense, honestly. He said "kid, cars rot from the inside of the air, not the outside." So I left a box there mostly to shut him up, and when I checked it two springs later that thing was a rock and the chrome on my bumpers stayed way cleaner than my buddy's Firebird across town that sits in a shed with no air flow. Now I buy the big boxes. Turns out he wasn't wrong, I was just too stubborn to hear it. What do you all use in a garage that gets humid but cold? Baking soda feels like the cheap fix but I want to know what else actually works.
