I have noticed over the last year I have been ruining all or dark clothes, black things turning a greenish colour in particular and jeans losing colour in places, my whites however are sparkling! So what do you use and in what form? Same for everything or different products for different loads? I have lost 3 stone so need all new autumn winter clothes and my fav jeans are Next 360 Jeans which are £45-£50 a pair depending on rinse and style so I would like for them to not fade and go a funny shade of green after a few washes. Oh and the dark care cycle on washing machines does it actually work?
