As we have already told you that polyester is the best material for glow in the dark blanket. Additionally, it is also one of the softest blanket materials that offer you super comfort. Vinegar usually helps in maintaining the fluffiness of the blanket.
So, make your polyester fabric new again by washing them with white vinegar instead of detergents. The vinegar cuts through the build-up to make the blanket soft and new again.
