That's an excellent and very specific question! For a trash can to truly withstand regular power washing, you need to look beyond typical residential models. The key is finding a unit built for commercial or heavy-duty municipal use. Based on durability and material, the best models are typically constructed from heavy-gauge stainless steel (type 304 or 316) or high-density polyethylene (HDPE).
For the absolute best power wash performance, a fully welded, seamless stainless steel bin is the top choice. The 304 stainless steel offers excellent corrosion resistance, and the seamless construction means there are no cracks or crevices for water and debris to penetrate. Look for models with a reinforced base and a smooth, rounded interior. Brands like Toter, United Receptacle, and Glasdon offer commercial lines designed specifically for high-pressure cleaning in urban settings.
If stainless steel is beyond your budget, a rotationally molded HDPE plastic bin from a reputable commercial brand is a strong contender. These are impact-resistant and won't rust. Ensure it has reinforced walls and integrated drainage holes at the bottom to let the high-pressure water flow out quickly. Avoid bins with multiple seams, glued parts, or thin plastic.
Regardless of material, check that all openings (like the swing lid) are designed to prevent water ingress and that any metal components (hinges, bolts) are also corrosion-resistant. Your best bet is to search for "commercial grade," "municipal," or "heavy-duty" trash cans, as these are engineered for the harsh cleaning routines of city maintenance crews.
