Coverlet vs. Blanket: Washing Tips for Longevity
Coverlets, since they do not touch the skin as often as sheets, only need washing about once every two months. This helps them stay fresh without unnecessary wear.
Blankets are used more often, so their washing frequency depends on use and preference. Generally, wash blankets at least once a month, and clean them immediately if they get dirty or pick up odors.
