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.
