I currently have a Threat that I have yet to clean since I purchased. As much as I tend to clean and maintain my equipment, this is totally unacceptable to me, however, I have a slight problem when it comes to cleaning. All that I have for cleaning equipment is Hook-It, which, no matter what Neo-Tac says, DOES dull shiny equipment. Is Renew-It a product that I should be looking at for this particular ball?
