That's an excellent and very practical question! The short answer is: yes, you absolutely can power-wash most outdoor trash cans, but doing it *correctly* is the key to avoiding damage. It's one of the fastest and most effective ways to blast away grime, sticky residues, and odors.
Here’s how to do it safely:
1. Check the Material First: Most modern outdoor bins are made from durable, UV-resistant plastics like polyethylene or polypropylene, which can handle a power washer. Metal cans (galvanized steel) are also typically fine. However, avoid high pressure on thin, brittle, or older plastic that might crack, or on any can with significant rust.
2. Use the Right Pressure and Nozzle: This is the most critical step. Never use a zero-degree (red) nozzle—it's like a laser beam and will cut into the plastic. Instead, use a wide 25- or 40-degree (green or white) nozzle. Start on the lowest pressure setting (around 1200-1500 PSI) and hold the wand at least 12-18 inches away. You can move closer gradually if needed, but high pressure up close can dent metal or leave marks on plastic.
3. Pre-Rinse and Use a Mild Cleaner: Rinse out loose debris first. For tough stains or smells, a pre-treatment with a mild detergent, baking soda paste, or a dedicated bin cleaner helps. Let it sit for a few minutes before washing. Avoid harsh chemicals like bleach in high concentrations, as they can degrade plastic over time.
4. Mind the Gaps and Seals: Direct high-pressure streams away from lid hinges, locking mechanisms, or rubber seals to prevent forcing water inside or breaking them. A gentler spray is best for these areas.
5. Dry Thoroughly: After washing, leave the bin upside down or with the lid open in the sun to dry completely. This prevents mildew and keeps it smelling fresh.
So, go ahead and use that power washer! It’s a fantastic tool for the job. By following these simple tips—using a wide nozzle, low-to-medium pressure, and keeping a safe distance—you’ll have a sparkling clean bin without any harm. Your neighbors (and your nose) will thank you
