I would like to clean it but just enough to remove the surface rust color. Id prefer to not clean it down to shiny steel. Whats the cheapest least invasive way.
Wow, thats great, how did you find it? I see no numbers on the wrench, also how do I print all the patent data, I dont even see how you were able to save it and paste it here, when I right click I just have an option to print entire pages.
