How do I dispose old paint?

Spray Paint Cans:  should be completely void of paint by spraying out all paint until the spray paint can is empty.  Once the spray paint can is completely empty, it can be placed in with your normal trash.

Paint Cans:  harden paint by mixing kitty litter or another absorbent pellet material (such as Speey-Dri) in the can until no liquid remains. Air dry the paint and absorbent material until hard.  Once the paint is completely hard, place the can (without the lid) next to your garbage for pick-up.  Place the paint can lid in with your normal trash.  Hint:  The more absorbent material added to the paint can, the quicker the paint will harden.
