In January 2020 ImproveNet surveyed 4,326 people across the country about how they cleaned their home. They asked what was done, the time that was invested, and the level of detail that was employed. Out of 21 cities, Phoenix was ranked in the top five. What cities were the dirtiest? Milwaukee was deemed the least clean, followed by San Diego and Indianapolis. Clean homes sell quicker, so don’t let your home get dirty when its on the market.
