Cleaning Walls and Other Vertical Surfaces:
To clean dust and grime from vertical surfaces. begin by dusting the wall to remove cobwebs and dust. If the wall needs washing, wash with a mild cleaning solution, such as Fusol Degreaser moving from bottom to top. The reason for this cleaning method is that if a portion of the solution were to run down across a soiled area, it may leave a dirty streak that would be difficult to remove.

When cleaning walls and other vertical surfaces, remember to clean a small area at a time and take care to overlap the edges of the areas previously cleaned.
