Been there, done that. I have dozens of Rapidographs that have to be cleaned regularly when you are using them.
My kitchen sink has a disposal that my hand will not fit in, but my kids' will, so I get them to fish out small parts.
LOL... why have kids... if you can't put them into dangerous situations in your place...

My dad jokes with me. You're younger go do this for me. Then the whole family has this attitude "you see, this is why we have kids". Fetch beer from cooler go on the roof to tighten the satellite. Shove your hand in dark, slimy places.
