The back of one of my bottles of janola says rinse first, for outdoors use 1:4 and scrub with the mixture, leave 10-15 minutes and then rinse thoroughly. If you dont want to scrub then I would try 1:2 after rinsing first and applying to damp concrete.
Wet And Forget is specifically made for this sort of job.

Yes the Budget brand, and the cold water surf work well. As above wait until it rains, I've just done yesterday this by putting the soap powder with water until it dissolves in the watering can. and pour over the concrete, and it works well, though I prefer the rain method. Creates a nice smell as well.
