You can use a variety of products or cleaning solutions to wash your walls and remove dirt, grease, and odors. Most professional painters use TSP, or trisodium phosphate, to clean walls Just mix 1 cup of TSP to 20 cups of water or buy a TSP spray to apply to your walls and wipe with a washcloth. Be sure to use gloves when you're using TSP. Products like Zinsser Bullseye and Kilz are an essential step to removing smoke odors that have been around for a long period of time. Simple repainting will not remove the smell and will just trap smoke odors within the paint. For example, if an old piece of furniture smells smoky, you can wash it, prime it with a deodorizing primer, and paint it to get rid of the smell.
