I have recently moved in to a new home and decided that the bathroom color scheme would be all spa white. These towels are very substantial, and a lot bigger in size than I like for every day use, so have dedicated them for company use. It will be so convenient to have guest linen on hand. The washing instruction say not to use bleach on the long staple Turkish cotton. I obeyed for the initial washing and they are still like new. But, I bleach everything, and know I will not separate them from the white wash bleach, hoping they don't turn yellow or some other dastardly thing. Believe the directions are generically written to cover the many colors these towels come in and it is safe to use bleach. May be ordering another company set in color, when I decide what my splash color will be.
