Jeff Likes Clean Windows' eponymous glass de-grimer laves panes inside and out with the help of eco-friendly cleaning products. After scrubbing, Jeff slathers each porthole with a water- and pollen-repelling solution that keeps panes pellucid and facilitates clearer staring contests between homeowners and squirrels. Then, window tracks get denuded of grime before Jeff whips filth-laden screens back into bug-blocking shape with a training montage of sweat-inducing scrubbing and acts of tough love. Though not included in today’s Groupon, Jeff Likes Clean Windows can cosset clients' casas with additional services such as power washing ($0.10/sq. ft.), gutter cleaning ($1/sq. ft.), and cobweb removal (priced upon request).
