Removing sankharas

Can someone please explain to me in clear laymans terms exactly the steps to working with and removing sankharas because I think I have a lot. I have been meditating for 6 years and basically just using the breath as my anchor. When my mind wonders I note thinking thinking or seeing seeing etc then I come back to the breath. I'm not sure am I meant to do anything else? I don't really have any strong emotion arise in formal practice. It only happens in my daily life. To rewire the brain and remove sankharas am I meant to just notice sensation and not react? So someone cuts in front of me on the road and I feel a strong sensation of anger begin to arise. So I just watch it and know that it's anicca, Dukha , Annatta? And wait for it to pass? I must do this with all sensory inputs when I feel triggered? And then sankharas will be removed eventually? Is this correct?
