When washing a duvet cover, it's not uncommon for other items to end up inside it due to the agitating motion of the washing machine. Duvet covers are usually larger than regular laundry items like clothes or pillowcases, creating a "pocket" during the wash cycle. This pocket can inadvertently catch smaller items, such as socks or underwear, causing them to be trapped inside the duvet cover.
To avoid this issue, washing the duvet cover separately or with other large items like bed sheets or towels that won't get easily caught inside is best. Additionally, using a laundry bag or tying the duvet cover's openings with rubber bands can help prevent smaller items from slipping in.
If managing large duvet covers is a hassle, one can consider seeking duvet washing services. These specialised services can ensure proper handling and cleaning of duvet covers, maintaining their quality while eliminating the hassle of washing them at home.
