Take the stylus, dip it straight into the goo and lift it up and it will keep the dirt in the goo and won't leave a mark on the stylus. 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.
