Mold and mildew under vinyl flooring is a health concern. Mold needs to be identified, and if a problem persists or it has spread to the floorboards, you need to contact a mold remediation specialist. Cleaning up mold can be completed in a few easy steps, but the steps need to be followed meticulously.

Mold Cleaning Supplies

Cleaning Up Mold Under Vinyl Flooring

You must clean your gear when this project is complete to prevent mold spores from spreading. Thankfully, cleaning up mold is more of a meticulous process than a difficult one. Follow these four easy steps to clean mold under your vinyl flooring.

Step One: Spray Affected Area

Using the spray bottle containing the bleach and water cleaning solution, spray down the affected area. Allow the cleaning solution to sit for about 10 minutes. This will give the bleach a chance to break down and kill the mold.

  • ▷ITEM INCLUDED-Pack of 5 coveralls.Foot cover not included.

Step Two: Clean Using Scrub Brush

Spray some of the bleach and water solution directly on the scrub brush.  Then, use the floor scrub brush to clean the affected area. Repeat this process until your entire floor has been scrubbed and the mold has been removed.

  • Pro Tip: Always make sure your floor is wet with the bleach mixture to avoid spreading mold spores.

Step Three: Dry Flooring Surface Area

Once you have killed the mold, the floor must be dried. Since moisture helps facilitate mold growth, it is essential to dry your floor thoroughly, using your cleaning towels. Alternatively, you can plug in a blower fan to dry your floor or use a combination of both strategies.

Step Four: Clean Gear Thoroughly

After working with mold, it is important to clean the gear used for the task. Place the towels into the washing machine immediately and wash on the hottest setting. Use the bleach and water solution to clean the safety glasses, rubber gloves, and scrub brush. The N95 mask can be cleaned, or you can opt to throw it away if you have extra masks available.

  • Pro Tip: Air-dry your cleaning gear outdoors in the sun.
