Tips for basement clean-up include removing furniture and other items from the basement first, collecting cleaning products before starting the process, sweeping the floor with directed strokes, and using a cleaning solution to wash the floor and walls. Hand wash the floor to make it extra clean. Dust light bulbs and furniture before replacing them.
To clean the basement, clear it of items, and gather cleaning products at one central point. Dip a sponge in warm, soapy water, and use it to clean the outside parts of the furnace and water heater. Pour 1 teaspoon mild dishwashing liquid in a bucket, add 1 cup ammonia, fill the bucket with water, and mix to form a foamy solution. Insert a natural sponge into the solution, and use the sponge to clean walls, making sure to start at the bottom and to clean one small section at a time until you do the entire wall.
Scrub mold with a washing brush, wash away loose mold with soapy water, and rinse with clean water. Put 1 pint rubbing alcohol in a small container, add 1 spoon dishwashing liquid, fill up the container with a 1/4 cup ammonia, and stir the mixture. Put a sponge in the solution, and wipe the windows.
Apply baking soda to the floor and stairs to eliminate odor, and sweep with long, directed strokes. Next, vacuum smoke detectors. In circular motions, hand mop the floor with a dampened cloth. Be sure to sweep and mop the corners and edges first. Let the floor and walls dry completely before replacing furniture.
