What is the 80/20 rule for house cleaning?

The 80/20 rule, borrowed from the broader Pareto Principle, suggests that roughly 80% of a home’s visible cleanliness comes from focusing on just 20% of the total cleaning tasks — the high-impact, high-visibility areas rather than exhaustive, all-encompassing cleaning. For exterior cleaning specifically, this means prioritizing the areas guests and passersby actually notice first: the front entryway, driveway, visible siding, and windows, rather than spending equal effort on every square inch of a property. Applying this principle to pressure washing means tackling the most visible, highest-traffic surfaces first if time or budget is limited, since that’s where cleaning has the most noticeable impact on curb appeal. It’s a prioritization framework more than a strict formula, useful for deciding where to start when a full property clean isn’t realistic in one visit.
