Try out a Viking blue lug nut brush. I have most of the ones you have, the blue Viking, and anything in the Viking brand has been super quality. They sell them local at my O'Reilly's store. I have tons of Viking stuff, and every single thing I've been very impressed with quality and longevity. The rags too!
I appreciate your feedback! I will have to give them a shot. I love the viking brushes, and I love that I can get them right down the road. Take care and thanks for watching!
