Insulate the garage to create a vapor barrier and prevent humidity. Seal any holes or leaks to prevent moisture from entering the garage. It is better to treat the source of the problem rather than just tackling the symptoms.2
Place a dehumidifier in the garage to absorb moisture from the air. Empty the dehumidifier when it fills with water. If there's a window in the garage, place a fan in the open window facing outside to blow out the moist air. Ventilation can reduce moisture in the air.3
Hang cloth bags of silica gel or activated alumina in the garage or place open containers of silica gel or activated alumina on shelves to absorb moisture from the air. When they become full of water, discard them and refill the bags or containers.4
Install an air conditioner in the garage window, if possible. Cool, dry air from the air conditioner can reduce moisture in the summer months.Tips & Warnings
Find silica gel at craft stores or home improvement stores.
Keep silica gel or activated alumina out of reach of children and pets.
