Like any substantial innerspring upholstered mattress, the Aviya Mattress is not built to be immersed in water. For stains, we recommend spot cleaning only when necessary. If you have an area on the surface that needs attention, use a spray upholstery cleaner and soft cloth such as you might use on an item of furniture. It is recommended that you spot test such products as some might leave a yellowish stain on the surface ticking. You can also vacuum your mattress surface with a soft brush or plastic attachment. The best solution to keep your mattress clean is to prevent any stains. We recommend using an appropriate mattress protector to keep your mattress clean and stain free.
