Avoid contact with harsh liquids to keep the fabric intact. Harsh liquids include bleach, fabric softener, and strong detergents. These chemicals can cause the blanket to fade, lose durability, and damage the structure. Additionally, mistakes like overloading the machine and washing the blanket with rough fibers can damage the blanket.
Bleach may damage the color and structure of your polar fleece blanket. It consists of harsh chemicals that weaken the strength of the polar fleece fibers. As a result, the fibers break easily and lose their durability. Additionally, it can cause fading since it is a powerful whitening agent.
Fabric softeners can reduce the softness and moisture-wicking properties of a polar fleece blanket. Residues from chemicals can coat the blanket's fibers and change its texture.
The chemicals in harsh detergents can damage the blanket's synthetic fibers. This includes thinning, abrasion and breakage of these fibers. As mentioned before, avoid overloading the machine. This provides more space for the blanket to clean. Also, avoid washing blankets with rough fibers to prevent pilling and hot water to prevent shrinkage.
