Preserving Organic Wool and Linen Garments Without Mothballs

The Cedar Heartwood Thujone Mechanism

Only Eastern Red Cedar (Juniperus virginiana) containing active thujone oils discourages clothes moth larvae. Sanding cedar blocks once per season replenishes volatile oils.

Sun Bleaching & Natural UV Sterilization

Air-drying linen shirts in direct morning sunlight for 45 minutes eliminates odor-causing bacteria without fiber damage caused by chlorine bleach.

Breathable Cotton Garment Bags

Never store natural woolens in polyethene dry-cleaning bags, which trap condensation and trigger mildew colonies.
