Maybe a syringe would work. My ortho cleaned me out and it felt so good! She gave me a syringe to take home so I could rinse round the expander (with mouthwash or jusr water, depending). It dislodges some of the food bits. Also interdental brushes work to clean about above expander (as it sits slightly beloew the palate). I can't fit those through my teeth, but I use them to dislodge food and get into the crannies of my expander. Try it out anyway
