Decreasing Neonicitinoid in a store plant

Hey guys, a friend just gave me a lil lemon tree from Walmart. The label is proudly shouting that it's treated with Neonicitinoid. I know it's bad stuff, but is there somehow I can flush it out of the tree? Rinse the dirt off the roots? Water it with something that would neutralize it, like vinegar or baking soda?

Sorry, spelled that wrong. should be "Neonicotinoid"
