That's an excellent question! The short answer is yes, most outdoor trash cans and dumpsters can be cleaned with a power washer, but there are some important considerations to ensure you do it safely and effectively.
For commercial metal dumpsters and heavy-duty plastic bins, power washing is actually the most efficient cleaning method. The high-pressure spray easily removes sticky residues and eliminates odors that regular rinsing can't handle. Stainless steel and powder-coated metal containers typically withstand pressure washing well, though you'll want to maintain a reasonable distance (about 2-3 feet) to prevent damage to the surface finish.
When cleaning residential outdoor trash cans, use a wider spray pattern and lower pressure setting if your washer has this feature. Avoid directing the spray at seams or lids where water could penetrate and sit, potentially causing deterioration over time.
Always wear protective goggles and gloves, as power washers can splash back debris and bacteria. For heavily soiled commercial dumpsters, consider using an eco-friendly degreaser before pressure washing to break down stubborn grime.
The key is matching the pressure to the material - durable commercial containers handle higher PSI while residential bins need gentler treatment. With proper technique, power washing will keep your outdoor receptacles clean and sanitary for years to come.
