Assessing the Condition of Your Walls
Before diving into the cleaning process, it’s critical to assess the walls’ current state. Look for signs of discoloration, sticky residues, and stains, typical of cigarette smoke exposure. Identifying the problem areas will guide you on which cleaning methods to deploy and whether any wall sections may need more intensive care than others.

Understanding the Risks of Painting Over Dirty Walls
Painting over dirty walls can lead to peeling, uneven finishes, and the persistence of odors. Smoke residue can seep through paint layers, affecting air quality, which is particularly concerning with a young child. Additionally, unaddressed grime can degrade the integrity of the paint, causing a need for frequent repaints.

The Essential Supplies and Equipment for Wall Cleaning
To effectively clean your walls, gather supplies such as microfiber cloths, sponges, a long-handled mop for high areas, buckets, and protective gloves. You’ll need appropriate cleaning agents—such as trisodium phosphate (TSP) for tough stains—and household solutions like vinegar and baking soda. Always consider the type of paint on the walls, as this may dictate which cleaning materials to use.
