That's an excellent and very practical question! The short answer is: it depends entirely on the material and build quality of the trash can. Not all outdoor bins are created equal when facing the force of a power washer.
For standard, lightweight residential plastic or vinyl cans, using a power washer is generally not recommended. The high-pressure stream can crack thin plastic, force water into seams and mechanisms (like foot pedals), and strip away finishes or colors, leading to premature wear and fading.
However, many commercial-grade and heavy-duty outdoor trash cans are absolutely designed to withstand power washing. Here’s what to look for:
* Material is Key: Trash cans made from high-density polyethylene (HDPE) or, better yet, stainless steel (304 or 316 grade) are top contenders. These materials are non-porous, corrosion-resistant, and can handle high-pressure water without degrading.
* Construction Quality: Look for seamless, rotational-molded construction in plastic cans, which creates a single, water-tight piece. For stainless steel, check for fully welded seams and robust hinges. Cans with simple, sturdy designs and minimal crevices are easier and safer to clean thoroughly.
* Manufacturer's Instructions: Always check the product specifications or care label. Reputable brands for commercial and municipal use will often explicitly state that their products are "suitable for power washing" or "easy-clean surfaces."
Best Practices for Power Washing a Trash Can:
If your can is built for it, follow these tips:
1. Use a wide-angle (40-degree) nozzle and keep a safe distance (at least 12-18 inches) to clean effectively without causing damage.
2. Pre-rinse loose debris.
3. Use a mild detergent if needed, and always rinse thoroughly.
4. Avoid directly blasting hinges, locks, or liner mechanisms for extended periods.
In summary, while your average home trash can might not be a good candidate, investing in a heavy-duty, commercial-style outdoor trash can made from durable materials will ensure it can stand up to rigorous, sanitary cleanings with a power washer for years to come.
