Why You Should Put Marseille Soap Under Your Sheets: A Timeless Grandmother’s Trick

How to Use It Correctly

1. Choose the Right Soap
   Use authentic Marseille soap — pure, without perfumes or additives. Olive oil-based versions are ideal.

2. Cut into Pieces
   Slice the bar into smaller chunks to make it more versatile and long-lasting.

3. Wrap in Cloth
   Place the pieces in a light fabric, muslin bag, or old pillowcase to avoid direct contact with your sheets and prevent any residue.

4. Placement

   • Under the mattress, around leg level

   • Or between the sheet and mattress cover, near the feet

5. Replace Regularly
   To maintain freshness and effectiveness, replace the soap every 2–3 months.
