What do you call the stuff you use to wash clothes?
I know washing up liquid is detergent, used in washing dishes, but I don't know the proper name for the stuff used for clothes.
If it's powder, you can say washing powder right? But if it's a liquid? Clothes washing liquid sounds silly, washing liquid is ambiguous, and laundry detergent just sounds so weird and formal to me.
I keep trying different words, but English people (I'm in the UK) never understand what I'm talking about...
