I change bedsheets and pillows (white 100% cotton) once a week and wash them in biological washing powder. They are a few years old (ahem) but still in good nick so I don't want to replace them, but they are all grey in the middle. Pillows are particularly gross I am ashamed of my washing line. I've tried Glow White to no avail. Should I bleach them or what?
Can't quite believe I'm agonising about "keeping my whites white" but yes it has come to this.
Any suggestions gratefully received.
