Best Clothes Washing Cleaner?

I use Comfort Fabric Softener, if that helps.

Clothes smells lovely, and once ironed feel new again.

I agree 
Comfort is a great choice for making your clothes to have a good smells and make it soft too

After years of experimentation and sniffing bottles of detergent and softener in supermarkets, I have settled on the following:

Detergent: Persil Gel (blue liquid in clear bottle)
Softener: Downy, Feel Romantic flavor (pink bottle)

I traveled at the end of Feb and I when I returned in mid April, I opened my wardrobe and was blown away because the clothes still smelled great from the detergent and softener!  The detergent smells great, very fresh and breezy, and even if you don't use a softener, your clothes will smell great for days.  The softener has a sweeter smell, and the smell also lasts for a while.  And yes, it makes them quite soft to the touch, especially if you also use a tumble dryer.

Note that there are other better smelling detergents and softeners, but they are the specially imported ones which cost an arm and a leg, for example Tide liquid for SR. 60-70 or so, for a 1.5 litre bottle (Persil is SR. 42 for 3 litres), and several US-made Comfort and Downy softeners which smell out of this world but cost way too much.  There is a great selection of the locally made Comfort and Downy softeners which smell good enough and are a lot cheaper than the US-made ones.
