Ingredients

  • 1 cup Hydrogen peroxide (3%)
  • 1/2 cup Water
  • 20 drops Tea tree essential oil (Natural antifungal)
  • 1/4 cup White vinegar (Use separately, not mixed)
Safe for: tile, grout, shower curtains, sealed surfaces, glass

Why This Recipe Works

Hydrogen peroxide is a powerful oxidizer that kills mold spores and removes mold stains through a bubbling action. Tea tree oil is a proven natural antifungal that continues working after application to prevent regrowth. The combination provides both immediate kill and long-term prevention.

Instructions

  1. Make the spray: Combine hydrogen peroxide, water, and tea tree oil in a spray bottle.

  2. Pre-treat with vinegar (optional): For heavy mold, spray vinegar first and let sit 5 minutes. Wipe clean, then proceed.

  3. Apply peroxide solution: Spray the hydrogen peroxide mixture directly on mold. Saturate the area.

  4. Let it dwell: Allow to sit for at least 10-15 minutes. For heavy mold, leave for up to an hour.

  5. Scrub if needed: Use a brush on grout or textured surfaces.

  6. Don’t rinse immediately: Let the tea tree oil remain for continued antifungal action. Wipe clean after 30 minutes if desired.

Tips & Variations

  • Prevention spray: Use weekly in mold-prone areas to prevent growth.
  • For grout: Apply with an old toothbrush and scrub thoroughly.
  • Shower curtains: Spray both sides and let dry before using shower.
  • Caulk: For moldy caulk, this can help, but severely molded caulk should be replaced.

Safety Notes

  • Don’t mix peroxide and vinegar together: Use separately to avoid creating peracetic acid.
  • Wear protection: Use gloves and ensure ventilation when cleaning mold.
  • May bleach surfaces: Test on colored grout and fabrics first.
  • Pet safety: Keep cats away until surfaces are completely dry.

Storage

Store in an opaque bottle away from light. Hydrogen peroxide degrades in light. Use within 1 month for best results.
