Washing light colours

I throw everything in together these days. Would waste far too much water doing separate loads. It all comes out clean and bright.

If I just have a few white or pale coloured items I wash them together with a colour catcher and a none bio powder and have never had any problems.

I will put light colours in with my white wash but always use one of the colour collector sheets. All seems good.

I use Colour Catcher sheets too, they are good for cream and navy-striped tops as well.

I do three different wash loads.
Whites.
Pale, but not white enough to go in with the whites.
Darks.

The vast majority of my clothes are pastel and I use those 'Colour Catcher' sheets which seem to help. I've not noticed any strange patches so hope they will help for you.

Like Meryl I think this must be bleach from somewhere.

I think biological powders have optical brighteners in them and oxygen based bleaching agents so it’s probably safer to wash any non-whites in non bio or stuff for coloureds.

White patches on any clothing/ towels can’t come from white material. It’s bleach from somewhere.

My sister in law once said that whites turned grey if washed with anything coloured. So since then I have always washed them separately even if it means waiting a while to have enough to make it worth running the machine or even running it with very little in there.

I can't see how white washing would bleach out coloured fabrics simply by sitting next to them in the machine, though.

Seems a daft question but living alone I've always put light coloured clothing in with my whites to make a full load. I've now seen white patches on my light blue towels and am wondering if all coloured materials should be washed with laundry liquids for coloureds, no matter how pale.
