If you opt for a duvet cover over your comforter instead of using a top sheet, Holliday-Bell suggests washing it every two to four weeks alongside your comforter, depending on your individual preference and use. Although it might be tempting to leave your duvet cover unchanged for months due to the hassle of removing it, regular washing is just as crucial as laundering your sheets. Alternatively, you could switch to a top sheet and wash it along with your sheets weekly.
