That's a great question! A smelly outdoor bin is a common headache, but with the right approach, you can get it clean and keep it fresh. Here’s a natural and effective method I swear by.
First, pick a sunny day and move the bin to an open area. Put on some old clothes and sturdy gloves—this is a messy job! Empty any remaining debris. Then, give the inside a good pre-rinse with a garden hose to loosen grime.
Next, make a powerful, natural cleaner. Pour about a cup of white vinegar or baking soda (or both for extra power) into the bottom. Add a generous squirt of dish soap. Fill the bin about one-quarter with hot water from a kettle or hose attachment. Use a long-handled scrub brush with stiff bristles to scrub every surface, especially the bottom and lid. The vinegar/baking soda combo cuts grease and neutralizes odors at the source.
After scrubbing, tip the bin to drain the dirty water, then give it a thorough rinse until the water runs clear. This is where a pressure washer or hose nozzle works wonders to blast away all residue.
The final, crucial step is to let it dry completely in the sun before putting in a new bag. Sunlight is a fantastic natural disinfectant and deodorizer.
To prevent future smells, sprinkle a handful of baking soda in the bottom of a dry bin before each new bag. You can also place a few dryer sheets at the bottom or spray the interior occasionally with a diluted essential oil spray. Regular cleaning every 1-2 months, or immediately after disposing of particularly smelly waste, makes the task much easier. Stick to this routine, and your bin will stay surprisingly fresh!
