Machine-washable
If your quilt is made from cotton, wool or a renewable fibre such as Suprelle® Blue, it can easily be machine-washed and (normally) tumble dried, though you should always check the care label for specific instructions.
Due to the density of some quilts, it’s best to wash them by themselves. Quilts need room to gently agitate in the machine for a good and proper clean, uninhibited by additional items. When wet, quilts can also become quite heavy. Keep an eye on the wash cycle, as you may have to re-position the quilt mid-wash to rebalance the weight, especially in top-loading machines.
Many modern washing machines have dedicated cycles for washing quilts, so look out for those settings on your machine.
Importantly, thoroughly dry your quilt before putting: it back on your bed or into storage. Quilts still slightly damp can be a breeding ground for mould and mildew. If you can air dry your quilt in sunlight, this is ideal as the sun can naturally help kill bacteria.
