I also need to buy a load of bedding when I come out in March, again I was going to buy white. I think it is the make up of the material and the temperature it is washed at that will determine as to it going grey.100% cotton can be washed at high temperature and bleached without going grey, although it will shink slightly. The higher the polyester content 50/50, will not tolerate high washing temperatures or bleach and is impossible to iron if put on a hot wash.Does anybody know the price of those heavy cotton blankets used in hotels?
