Here are five low-cost, green cleaning methods and products:

1. Baking soda: Baking soda is a natural abrasive that can be used to scrub surfaces and remove stains. It's also an effective deodorizer, so you can use it to freshen up your trash can, sink, or other areas that tend to get smelly.

2. White vinegar: Vinegar is a natural disinfectant and deodorizer, and it can be used to remove soap scum, hard water stains, and other types of grime. Mix equal parts vinegar and water in a spray bottle to create an all-purpose cleaning solution.

3. Lemon juice: Lemon juice is a natural bleach and deodorizer, and it can be used to remove stains and freshen up surfaces. You can use it straight from the bottle, or mix it with water to create a cleaning solution.

4. Castile soap: Castile soap is a versatile, plant-based cleaning product that can be used to clean a variety of surfaces, including countertops, floors, and windows. It's gentle and non-toxic, making it a great choice for green cleaning.

5. Microfiber cloths: Microfiber cloths are great for dusting and cleaning surfaces because they're able to pick up and trap dirt, dust, and other particles. They're also reusable, so you can use them over and over again, which helps to reduce waste.
