Mindfulness issues

When I am practicing being mindful, for example when washing the dishes, there seems to be so many things going on at once that I kind of don't know what to focus on. There is the warmth of the water, the smell of the detergent, the sound of the water and sounds all around, sights out the window etc etc. I have this problem in general with mindfulness. Feels like many things pulling my attention in all different directions. Can someone please clarify for me how I should be doing this correctly because I feel confused about it.
