Care-Washing InstructionsAll our cotton bedding can be washed on a light cycle up to 40°C.Use a medium and not strong detergent - preferably liquid - for cotton fabrics. Do not use bleach. Remove duvet covers as soon as the washing machine is finished. This way you will avoid wrinkles and also problems with spots/bleaching from contact with other clothes. In the first 2 or 3 washes, turn the case "upside down" in the washing machine so that the good side does not come into contact with the washing machine bucket. This way you will avoid making lines in the pattern of the fabric.DryingPrefer natural drying (not in strong sun). It is possible to dry in a tumble dryer, on the corresponding programme.IronIron Iron at medium to high temperature. StorageFor storage, prefer fabric cases that allow your bedding to breathe and store in a dry place.
