Open all doors and windows in your home. Put door stops in the doors to encourage a cross breeze. This will help move out the smell quickly. Leave the doors and windows open as long as the weather will allow.
Fill bowls with white vinegar, and place them in several locations throughout your house. Place at least one bowl in each room that smells like paint.
Fill a bowl with activated charcoal, and place it in the center of the room that smells the most. The activated charcoal will absorb the smell and supplement the white vinegar treatment.
Place 2 tablespoons of cinnamon and an entire orange peel into a small pot.
Cover the cinnamon and orange peel with 2 cups of water, and bring the mixture to a boil. This will not remove the odor, but it will help cover it until the smell dissipates fully.
