To protect the conductive layer of your grounding sheet, you must avoid detergents and washing products that contain bleach, optical brighteners, whitening agents, heavy fragrances, oils or strong chemicals. These substances may coat or corrode the conductive threads and reduce the grounding performance.
You should also skip fabric softeners, dryer sheets or heavily scented laundry boosters. Fabric softeners and dryer sheets deposit residues that can block conductivity even after washing.
The safest choice is a mild, unscented detergent designed for delicate fabrics or sensitive skin. If needed, a small amount of baking soda can be used as a natural cleaning booster or to help with odours.
For spot-treating stains, use a gentle paste of baking soda and water and scrub softly with a damp cloth rather than relying on harsh stain removers.
By using only gentle, fragrance-free detergents and avoiding harsh additives, you help preserve both the softness and the conductive integrity of the grounding sheet.
