That's a great question! Dealing with odors from outdoor trash cans is a common hassle. Over the years, I've tried a bunch of methods and found some real winners. Here are my personal recommendations, from simple household items to powerful commercial products.
For a quick and natural fix, you can't go wrong with baking soda. Just sprinkle a generous amount at the bottom of your clean, dry can. It's a fantastic odor absorber. Another easy trick is to toss in a few dryer sheets with each new bag; they help mask smells pleasantly.
If you're looking for a dedicated product, I highly recommend deodorizer pods or discs designed for trash cans. Brands like Lysol or Febreze make ones that clip under the lid. They slowly release odor-fighting agents and last for weeks. For tougher, organic waste smells, an enzyme-based cleaner or odor neutralizer spray (like ones for pet odors) works wonders. A quick spritz on the bag and inside the can breaks down the source of the stink.
My top tip? Prevention is key. Always use a liner bag, try to keep the lid closed, and give the can a rinse with a vinegar-water solution every few months. Combining a good deodorizer with these habits will keep your outdoor area smelling much fresher.
