Using flour as a replacement for washing dishes is not recommended and generally not effective. Flour is a food ingredient and not a cleaning agent, so it won't effectively remove grease, oils, and food particles from dishes. Attempting to clean dishes with flour could leave behind residues and potentially contaminate your dishes, making them unsafe for future use.
For proper dishwashing, it's essential to use water, detergent, and appropriate cleaning tools like sponges or brushes. These will help remove food particles, grease, and bacteria effectively, leaving your dishes clean and safe to use.
If you are trying to find an eco-friendly or natural alternative to commercial dishwashing detergents, you can consider using a mixture of baking soda and vinegar, which can be mildly effective for light cleaning. However, for heavy-duty cleaning, it's best to use proper dishwashing detergents specifically designed for this purpose.
