Frequently Asked Questions

Are there DIY and natural mold cleaning options that don’t require bleach?

While there are alternatives to bleach, these DIY options below are not registered by the EPA to kill mold. Any product that kills mold needs to be registered with the EPA like Clorox Disinfecting Bleach. However you may try these options for cleaning mold stains:

  • Vinegar: Spray white vinegar onto mold stain, let it sit for an hour, then scrub and rinse.
  • Hydrogen peroxide: Apply 3% hydrogen peroxide directly on moldy areas. Let it sit for 10 minutes before scrubbing and rinsing with warm water.
  • Baking soda: Mix baking soda with water to form a paste, apply it to the mold, scrub, and rinse.
Are there additional mold and mildew tips for bathroom surfaces?

Here are some things to consider when cleaning mold in the bathroom.

  • Moldy caulk: If mold is embedded in cracked caulk, consider removing and replacing it, as it’s challenging to clean once mold gets inside.
  • Painting over mold: Don’t paint over mold, as it will eventually bleed through the paint. Always remove mold, then clean and dry the area thoroughly before any painting.
  • Tile and grout care: Regularly clean and reseal tile and grout to maintain a mold-resistant surface.
