I recorded several episodes in my car today - so I just grabbed a few things to use.  I grabbed a wooden bowl - almost heart shaped and would be the size of a salad or cereal bowl.  Then I have what would be a soft dish scrubbing brush, another one that is made of plastic bristles, and the third one is classified as a pet lint brush - but is also made of plastic bristles.   I liked that last one so much- I ended up making another episode of it by itself.  I use the brushes next to the microphone and sometimes right on the microphone.
