Remove items from the walls. Keep these items -- such as framed pictures and wall decorations -- in a safe location during the cleaning process.
Pour 3 gallons of warm water into a 5-gallon bucket. Add 1 cup non-sudsing ammonia, and 1/4 cup liquid dish soap -- that does not contain bleach -- to the water. Mix the contents with a long-handled spoon. Fill a second bucket with cool water.
Saturate a sponge in the mixture. Wring out the sponge to remove excess liquid. Begin at the bottom of the walls, and scrub in a circular motion while working upward. Starting at the bottom will help eliminate drip stains.
Rinse the sponge in the bucket of clean water when it becomes soiled. Submerge it back into the cleaning mixture, wring out the excess liquid, and continue scrubbing approximately a 3-foot by 3-foot area of the wall.
Fill another bucket with clean water. Dampen a cloth in the water, and rinse the cleaning mixture from the 3-foot by 3-foot area of the wall.
Use a clean towel to dry the water from the wall. Continue cleaning in 3-foot sections until you have cleaned all the walls.
