My baby is 2 months old and may i know what should be the correct way of washing the milk bottles after each use?

1) Wash the milk bottles with tap water
2) Put all the washed bottles into a small pail with water and drip some Kodomo Cleanser for Baby Bottle & Accessories into it and scrub with a brush bottles by bottles.
3) Lastly wash thoroughly the soap away.
4) Place into the sterliser .

Is this the way how all the mummies wash the milk bottles? Is this the correct way?
