Dehumidifiers for Vintage and Classic car preservation.

Preserving vintage & classic cars with a dehumidifier, in a garage, is indeed a crucial task, and maintaining the right humidity level is a key aspect of this preservation. High humidity can lead to rust, mould, and corrosion, while low humidity can cause problems like cracked leather and faded paint. Here are some tips on using dehumidifiers to protect your vintage or classic car in the garage:

Choose the Right Dehumidifier: Look for a dehumidifier that is appropriate for the size of your garage. Vintage & classic cars often occupy larger spaces, so you may need a more powerful unit. Dehumidifiers are typically rated by the amount of moisture they can remove in a day, usually in pints (USA) or litres. Typically dehumidifiers sized 24-30-40L/day for small 1-3car garages or  50-150L/day dehumidifiers for larger showroom areas from 3-10 cars.   

Positioning: Place the dehumidifier strategically in the garage to ensure even distribution of dry air. Consider using multiple units and wall fans to evenly move dry air, if your garage is large or has multiple storage areas.

Keep the Garage Closed: Make sure the garage is properly sealed to prevent outside humidity from entering. Weatherstripping doors and sealing any gaps can help maintain a controlled environment.

Regular Maintenance: Clean and maintain the dehumidifier according to the manufacturer's instructions. This ensures its effectiveness in removing moisture from the air.

Monitor Humidity Levels: Invest in a temp/humidity meter to monitor humidity levels in the garage. The ideal humidity level for classic car storage is typically between 40% and 50%. Adjust the dehumidifier settings accordingly to maintain this range.

Consider a Desiccant Dehumidifier(shown): In extremely cold conditions, a desiccant dehumidifier may be more effective than a refrigerant-based one, as it can operate in lower temperatures. typically from SYD up to Cairns use refrigerant type, whereas Victoria and Tas may need desiccant models, as they can be much cooler during winter.

Use a Timer: Some dehumidifiers come with timers, allowing you to set them to run only during specific times when humidity levels are likely to be higher.

Ventilation: Ensure some level of ventilation in the garage to prevent stagnant air. However, be cautious about introducing outdoor air when it's very humid outside.

Store the Car Properly: When storing your Vintage or classic car, use a car cover to protect it from dust and debris. Elevate the car slightly off the ground to prevent moisture from the concrete floor from affecting the vehicle.

Regular Inspection: Periodically check your classic car for any signs of rust, mould, or corrosion. Catching these issues early can prevent costly damage.
