Cleaning walls is essential, especially after buying a home with visible grime or smoke stains. Painting over dirt can lead to peeling, odors, and poor air quality—so always clean first.
1. Assess Wall Condition:
Look for discoloration, sticky residue, or smoke stains to determine which areas need deep cleaning.
2. Don’t Paint Over Dirt:
Smoke and grime can seep through paint, cause odors, and shorten paint life.
