Radia Smart Shielding Fabric does not lose its effectiveness when accidentally put in the dryer. Radia Smart shielding fabric is made from highly conductive material. Going forward, we recommend following the wash instructions.
Washing instructions: Hand wash preferred or gentle machine wash in cold water. Use gentle (phosphate-free) detergent. Air dry. Do not tumble dry, dry-clean, bleach, or iron. If washed according to these directions and kept free of mechanical and chemical stress, the radiation shielding blankets should retain their shielding effectiveness indefinitely.
