Mold/Mildew Removal

Removing Mold and Mildew with Bleach

If black spots are appearing on your walls or floor, you might have a mold or mildew problem. For non-porous materials, bleach can kill almost every type of indoor mold and its spores that it comes into contact with. It is the best chemical solution for sanitizing the surface and resisting future mold growth.

Follow Safety Procedures

Keep children and pets out of the area until mold removal is complete and you’ve determined it’s safe for them to enter the affected area. It is important to read and follow the safety instructions on the products you’re using prior to the mildew and mold removal. When using bleach, never mix it with ammonia or any other cleaner. Wear rubber or other non-porous boots, gloves, and eye protection. Try not to breathe in fumes from the sanitizing products. When using the cleaning products inside, open windows and doors to ventilate the area if possible.

Remove Water and Debris

Before you can begin the cleaning and sanitizing process on your floors, you need to remove the water and debris. Unger Professional™ floor squeegees are ideal for removing large volumes of water or debris and can be used on a variety of surfaces such as asphalt, tile, concrete, and linoleum. They are commonly used for both residential and commercial tasks when there is a lot of surface area to clean and dry.

Thoroughly Clean Area

For mildew and mold removal from your wall or floor surface, you will need to use a strong bleach concoction. Mix 1 cup of bleach for every 1 gallon of water in a bucket. To wash the floor surface with the bleach mixture, use a heavy duty brush such as the Unger Professional HydroPower® Bi-Level Scrub Brush or Unger Professional Outdoor Scrub Brush. These brushes have strong bristles that can scrub tough stains and dirt. These brushes also attach to a water flow pole so that it is easy to rinse the surface with clean water from a hose afterwards.  Allow the floor to air dry.
