So I purchased new hot racing steel gears and input shaft with a hot racing aluminum carrier case, the stock case holds Metal Gears inside of it when I pull those out I want to clean them can I soak them in gasoline to clean them because I don't have a hobby shop anywhere near me, this 550 has been upgraded and runs 85 + mph on 4s lipo so I just literally tore up the input gear of the stock differential that's why I'm upgrading any help would be greatly appreciated before I start upgrading to steel and aluminum differentials
