Paint Cans (Empty) Put in Recycling Cart/Bin Dry Out and Recycle Make sure paint cans are completely empty and dry. Recycle with the lid off because this shows that the can is completely dry. Keep If Not Empty If the can is not entirely empty, store it for future use. Once a paint can is opened, it will last for two years, but an unopened can of oil, acrylic or latex paint can last for over 10 years.
