How do you get rid of aphids on basil plant?

So happy ! I just cured my indoor basil plant which was suffering from white little aphids all over it!! All I did was dunk the stem and leaves of the plant into a solution of Oak leaves and water. I did this once a day for 2 days. ( 99.99% cure after the first dunk !) (I had a bunch of oak leaves which I had previously torn up in to shreds and soaked overnight in a large bowl of water .) Also I changed the plants location to the bathroom (away from 2 other plants it was with ?not sure if relevant??!)- Lawrence
