Dust the entire wall with a duster to remove loose debris. Start at the top of the wall and work down.
Fill a bucket with warm water. Fill another bucket with warm water and a squirt of liquid dishwashing soap, or mix a bleach-free all-purpose cleaner with warm water according to the labels instructions.
Submerge a clean cloth in the cleaning solution and wring it out well.
Scrub the wall in approximately 3-foot-square sections using the cloth and cleaning solution, working in a circular motion from the bottom up to prevent streaking. Rinse each section immediately after washing it with a clean rag and the clean water from the bucket.
Dry each section promptly with another clean rag or towel.
Repeat this process of washing, rinsing and drying the wall in small sections until the entire wall is clean. Move on to the next wall in the same fashion.
