Keep White nylon/poly-cotton garments white?
Hello All. I am new here as of today so excuse me if this has been posted elsewhere.
I have a lot of white nylon clothes that are starting to grey in the wash. I also have a lot of polyester/cotton blend shirts that are also graying. I have always followed the label (wash in cold, no bleach, dry low, remove promptly, low iron etc.) but they still are grey. I have tried many detergents including Tide, Purex, Arm & Hammer, Gain and Cheer to no avail. I never use any additives because they are so delicate and wonder if there is a way to get them white again. My washing machine is European (I live in England) and can do a full wash up to 95C/205F. I would never wash this hot on nylon, but do i have to use a higher temperature to get them clean?
Any Help Much appreciated. Thanks
