When you have an unsealed concrete floor in your basement, garage, shed or other similar space, it is important to know how to clean the floor properly. You want to use mild ingredients that will not scratch or damage the concrete, while still removing all of the build-up that accumulates on the floor. By making an inexpensive cleaning solution at home, you save yourself a trip to the store plus provide yourself with a cleaning solution that works well and dries streak-free.

Sweep the concrete floor with either a broom or vacuum cleaner.

Mix 2 tsp dish soap, 1 cup white vinegar and 1 gallon warm water in a bucket.

Dip the mop in the bucket, squeeze out the mop and wipe across the unsealed concrete. The dish soap removes residue, while the vinegar disinfects and removes odour. The vinegar also works well in removing mildew, making it perfect for use in damp spaces.

Let the floor air dry after mopping.

Sprinkle baking soda over any fresh spills or stains, and scrub in with a nylon brush. The baking soda draws out the stain without damaging the unfinished concrete. Mop the area after removing all of the stain, to collect the baking soda.
