The answer to 'difference between window cleaning' is that there are two main types of window cleaning services: interior and exterior window cleaning. Interior window cleaning focuses on cleaning the inside of windows, while exterior window cleaning focuses on cleaning the outside of windows.
Interior window cleaning is typically easier and less time-consuming, as it does not require ladders or specialized equipment. It is also generally less expensive than exterior window cleaning. However, exterior window cleaning is necessary to remove dirt, grime, and other buildup that accumulates on the outside of windows over time. Exterior window cleaning can be more challenging and may require the use of ladders, squeegees, and other specialized tools.
