If the paint is latex-based, you can take up to 5 gallons to a Special Waste Drop-off Site. For a list of sites, click here.
Recycle empty metal or plastic latex paint cans.
If the paint is oil-based, you can put small amounts in a black garbage bag mixed with kitty litter, newspaper, or another absorbent material that will soak up the paint.
To dispose of a large amount of oil-based paint, contact a private hauler or an environmental services company.
