Take the needle, dip it straight into the gunk and lift it up and it keeps the dirt in the gunk and doesn't seem to leave any gunk on the needle. The instructions say to be careful to run the needle straight down and straight up, and I do it carefully. The photo shows the places I did it and it captures all the dirt on the needle very well. Better or worse than just using a brush on a needle I really don't know, but it's a fun alternative and makes a lovely gift. I like it. I give him 5 stars.
