Yes you can clean The Curetube. We suggest blowing out loose particles with an air compressor and wiping clean with a non abrasive towel and isopropyl alcohol. However a more efficient way to use The Curetube is to use our CureSack, Curetube liners.
When cleaned and stored properly The Curetubes can be used for years. In fact we have users still using their same tubes since 2017.
