Cleaning a house involves several steps to ensure every surface is thoroughly cleaned and sanitized. Here is a detailed guide on how to clean a house effectively: 1. Start by decluttering and organizing each room. Pick up items that are lying around and put them in their designated place. Throw away any items that are no longer needed or donate them. 2. Dust all surfaces, starting from the top and working your way down. Dust ceiling fans, light fixtures, shelves, and other surfaces using a microfiber cloth or a duster.
