Oak Park's bermuda and St. Augustine lawns shed prolifically from April through November. Pair that with weekly mowings and a weekly green-bin pickup, and the green bin sees more organic volume than the trash bin by a 3-to-1 ratio.
That volume produces a brown sludge at the bottom of the green bin within 60 days. The sludge is a mix of grass, broken-down leaves, and water from morning irrigation that drips off clippings. It smells like compost — because that's what it is.
A green-bin deep clean uses the same 200°F pressure-wash but adds a longer enzyme dwell time (15 minutes vs 3 for trash bins) to break down the cellulose-based residue. We also flip the bin to drain completely before rolling it back to storage.
Most Oak Park customers schedule green-bin deep cleans quarterly, with extras after major yard projects. Oak Park bin cleaning covers all three bins — black, blue, green — on the schedule that fits your yard.
