Default Dehumidier question

My car is a sunday driver / show car, I drive it but only on nice weather days, no rain or cold weather days. I keep it dry as possible to keep it clean and prevent rusting. My question is I keep it in a non climate controlled garage with a cement floor, will a dehumidifier help keep the area drier and help prevent rust and pitting of the chrome.

I dont see how it would hurt, being a college student, right now i am obligated to keep my car out in the elements since i have no garage at my apt. But since covering it doesn't do much from the florida humidity, i use a dehumidifier bag in the car. I dont remember what its called, but they are designed to be hung up in a closet and keep the clothes dry and what not, but the hook on the bag hangs on the coat hook in the car perfectly and it keeps the car dry and also makes it smell nice, its crazy to see how much water it absorbs, especially over the summer.

Absolutely it will help. Try to keep it below 40%. You may find that most machines will require a certain minimum room temp for them to work properly.

Also use something to absorb the moisture inside the car. The moisture that gets in goes everywhere including inside the gauges.

Your garage will need to be well sealed. You want to take moisture out of the air inside the garage and not be continually pulling outside air inside.

Thats why the clear bubble enclosures has interested me. I think if done right you could have a safe environment for the car and not break the bank in electric bills.

I run a dehumidifier when the humidity level exceeds 50%. I also run a heater tied into a thermostat and maintain 50's in the winter. Summer is when you get most of the humidity in the Northeast except for days like this with the remnants of Tropical Storm Ida blowing through.

When I winterize my boat I put dampaway buckets all over the boat including the cedar closets.

Even though the buckets are always filled with water I question the effectiveness of using them. As moisture is removed from the boat as soon as the humidity in the ambient air changes or more outside air is drawn into the boat, more moisture needs to be removed. Also as the temperature goes up from a cooler temperature it extracts moisture out of the air and onto surfaces.

An ideal set up is a constant 70*F and 50% relative humidity. Don't go under 50% because you don't want to dry out rubber seals, tires, hoses, etc.

A dehumidifier is a waste of money in a garage. Or even a house in the winter.
