How to Get Sheets White Again
If your sheets accidentally turn grey after a wash (maybe you mixed whites with a rogue red sock), don’t panic. Re-wash them with a cup of white vinegar in the rinse cycle, then hang them in the sun.
Still grey? Bluing agents are a thing—tiny blue particles that trick the eye into seeing white. A few drops in the wash, and people will think you bought new sheets. Shhh, our secret.
