Seconding this. Have been using the same JBC tips for 4 years with great success. When using the brass wool, I tend to lightly rest the tip in a clean area. Maybe sometimes I will rotate it a few times, but I never use pressure or make wiping or scrubbing motions. I'm not sure if it really matters though (ie. how do the hardness of the tip plating and the brass compare?).
