That's an excellent and important question! Keeping public bins clean is crucial for community health and reducing pests. Here’s a practical, step-by-step method that balances effectiveness with safety for the person cleaning.
First, safety is paramount. Always wear personal protective equipment (PPE): heavy-duty rubber gloves, safety goggles, and a mask (an N95 is ideal). Wear closed-toe shoes and old clothes. Choose a time when the bin is less full, if possible.
Start by emptying the bin completely. Remove all trash bags and debris. Give it a good preliminary rinse with a garden hose or pressure washer on a low setting to remove loose grime. This pre-rinse makes the deep clean more effective.
Next, apply a cleaning solution. For general cleaning, a mixture of hot water and dish soap or a dedicated all-purpose cleaner works well. For tougher grease or residue, a solution of baking soda and vinegar can be effective and eco-friendly. Use a long-handled scrub brush with stiff bristles to thoroughly scrub the entire interior and exterior, paying special attention to the lid, handles, and the area around the opening where contamination is highest.
After scrubbing, rinse the bin thoroughly with clean water to remove all soap residue.
Now, for disinfection. Cleaning removes dirt, but disinfecting kills germs. Apply an EPA-registered disinfectant suitable for outdoor use. Diluted bleach (a mix of 5 tablespoons of household bleach per gallon of water) is a common option. Ensure the surface remains wet for the contact time specified on the product label—usually 5 to 10 minutes for bleach. Do not mix bleach with other cleaners, especially ammonia.
Finally, give the bin one last rinse with plain water to remove disinfectant residue. Leave the lid open to allow it to air dry completely in the sun, which provides additional natural disinfection.
Dispose of your gloves and mask properly and wash your hands thoroughly. Regular maintenance on a weekly or bi-weekly schedule, depending on use, is the best way to prevent severe buildup and control odors and pests.
