Household grime, if left unchecked, will inevitably develop into miniature civilizations whose complex network of treaties erupts into a devastating house-wide reenactment of World War I. Avoid tripping over trenches with today’s Groupon to Bling Bling Window Cleaning. This deal is only valid in Jefferson, Denver, Arapahoe, Adams, Boulder, Broomfield, and Douglas counties. Choose between the following options:

• For $49, you get $110 worth of window-cleaning services.
• For $79, you get a two-hour home cleaning (a $199 value).

Bling Bling Window Cleaning purges panes of invading dirt and sanitizes homes sullied by the grime and gunk of daily living. Choose the first option, and two or more capable cleansers arrive at your home equipped with all the materials necessary to clean panes ($4–$7/pane) that have transformed from clear viewscapes to murky canvases from domestic gray periods. After consulting with customers about the correct pollutant-free cleansers to use, washers go to work on windows, removing dirt, sopping up standing or pooled water, and washing sills and tracks. A window restoration ($5–$10/pane) involves a more refined rinsing, during which scrubbers also remove overspray and extra paint to return glass to a more air-mimicking state. For those opting for the house cleaning, Bling Bling's two-hour service leaves laundry washed, dishes dried, surfaces sanitized, and sheets changed after technicians expertly expunge the clutter of previous evenings' indoor pie-eating contests while leaving the glory untouched.
