Somebody got the panties in a bunch.
Spend my money??? How much money are you talking? it's a few dollars for the Mad Scientist product, this thread is about. Starting from $25. Twenty five US dollars for the smaller bottle. What the big fuss?
By the way, calling contact / connector hygiene & maintenance bull crap (to quote your words) is a bit of rich. Garbage? Why the anger dude? Listen, you don't have to spend any money at all on anything, that's fine, not my business. But taking care of my contacts is something that is always advisable, and, one does not have to spend too much money. I have done it for two decades, just using stuff from the hardware store. Dremel tool, Brasso metal polishing liquid, soft cloth, and then apply contact enhancing fluid such as Caig DeoxIT, deoxIT Gold, or Jena Labs fluid. All very cheap and they work. For a few dollars. How is this "garbage" and "bull crap"?? You guys are very funny
