		 be careful with pipe cleaners. I used to use them to clean out the bottom of my siphon feed Iwata where you attach the color cup.  One day I found lots of little fibers plugging up my nozzle.  A real pain to clean out.  Stopped using them.  I now use those little interdental ? brushes you get in the flossing section of the store.  They don't come apart.
