Good day!, its raining today which means its maintenance day on the r1, picked up a set of NGK spark plugs to put in, i noticed some rust inside the spark plug wells, its not much but pooled up to one side, i tried spraying them with air but it wont budge, im gonna pick up a small brush to see if that will move it but is there anything i can spray in there to clean it?

no rush on this and i will definitely wait till its clean before removing the spark plugs.
