I too still sort my washing.
Bedlinen, towels, underpants, dish-cloths and tea-towels go on the shortest hotest cycle with appropriate laundry soap and water softener.
Dark clothes with laundry soap for dark colours washed on short cycle at 30 degrees.
Dusters, floor-cloths mops and other cleaning cloths washed when there are enough of them to fill the machine on short 40 degree cycle. Ifit takes to long to fill the machine with this category, I steep cloths overnight, rinse and scald them and hang them out.
New clothes (rare occasion these days) washed with same colour only, as the colour is almost bound to run,
Woollies washed on cold cycle only.
I never use fabric softener, as I am allergic to it, and as I sort in colours I have never considered the added expense of colour catchers.
