I feel like I'm totally cacking up this washing powder malarky at my great age .
I have :
Bio (green box) which I use for whites because I thought it had active ingredients like bleach
Non-Bio (blue box) which I thought was for gentle washing , like light colours and soft things
Colour(purple box) for colours and black , no bleach in it .
Sensitive (pink box) I don't know why , no-one has sensitive skin but I use it on things that are fragile
Eco Egg for wool
Then I read about the temperature which will activate or not if the powder needs to be at a given temp
Or too high will stop it working ..... and I'm now confused .
So- how does it work?
