<bot>: 
1. Start by gathering the supplies that you need including a bucket, cleaning solution, a sponge, microfiber cloths and a squeegee.
2. Fill the bucket with warm water and add a few squirts of cleaning solution.
3. Submerge the sponge in the solution and wring it out before using it to clean the wall.
4. Pay extra attention to corners and crevices, as these areas tend to accumulate dirt.
5. Rinse the cloths often in the cleaning solution and wring them out before continuing.
6. After cleaning, use the squeegee to wipe down the wall in long, vertical strokes.
7. Finish by wiping the area one more time with a dry cloth.
