That's a great question! The short answer is yes, you absolutely can power wash an outdoor trash can, and it's one of the most effective ways to deep-clean it. However, doing it incorrectly can definitely cause damage. The key is all in the technique.
First, check your trash can's material. Most modern outdoor bins are made of durable, high-density polyethylene (HDPE) plastic, which can handle a power washer if you're careful. Avoid using a pressure washer on very old, brittle, or metal cans with rust spots, as it can strip paint or crack the material.
Here’s the safe way to do it:
1. Pre-Rinse and Pre-Treat: Empty the bin completely. Give it a quick rinse with a garden hose to remove loose debris. For tough grime or odors, spray the interior with a diluted all-purpose cleaner, a vinegar solution, or a dedicated bin cleaner and let it sit for 5-10 minutes.
2. Choose the Right Nozzle and Pressure: This is crucial. Never use a zero-degree (red) nozzle, as its pinpoint jet can cut into the plastic. Opt for a 25-degree (green) or 40-degree (white) wide-spray nozzle. If your washer has adjustable pressure, start on the lowest setting.
3. Maintain a Safe Distance: Keep the wand tip at least 12-18 inches away from the surface of the can. Start from a greater distance and move closer only if needed. Use smooth, sweeping motions.
4. Mind the Angles: Avoid aiming the stream directly at seams, lids, or wheels where water can be forced inside and damage hinges or mechanisms. Angle your spray to glide over surfaces.
5. Dry Thoroughly: Let the can air-dry completely in the sun with the lid open before putting in a new bag. This prevents mold and mildew.
By following these steps, you can blast away dirt, sticky residues, and bacteria without harming your bin. A regular power wash can extend its life and keep your outdoor space smelling fresher. Just remember: low pressure, wide spray, and plenty of distance are your best friends for this messy job.
