Set of 4 sheets by Saint Clair Paris made of 100% cotton. The set consists of two sheets and two pillowcases. Care-Washing Instructions:All our cotton bed linen 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 the sheets when the washing machine is finished. This way you will avoid wrinkles and problems with spots / stains from contact with other clothes.In the first 2, 3 washes put the sheets / cases "upside down" in the washing machine. If it is a case, turn it upside down so that the good side is not in contact with the washing machine bucket. This way you will avoid making lines in the pattern of the fabric.Drying:Prefer natural drying. It is possible to dry them in a tumble dryer on the corresponding programme.(Dry them naturally not in strong sun or in a tumble dryer at medium temperature)Iron:Iron at medium to high temperature.Iron the sheets first from the reverse side and then from the good side. This way you will need less time overall to get a perfect result.Storage:For storage, prefer fabric bags that allow your bedding to breathe and keep them in a dry place.For long term storage (more than 3 months) it is very important to wash, dry, iron and store them in a cotton fabric bag.
