Zac James Nicholson Posted August 2, 2024 Posted August 2, 2024 I recently removed the 400' spools on my XTR magazines to shoot 100' rolls. One of the two has copper oxidation on the screws as seen in the photo. Before I do anything to clean it off, I wanted to check and see if there is anything I should put on the screws to prevent further oxidation, with the obvious consideration that I wouldn't want any product to leach out and potentially interact with the film down the line. Thanks for any help!

Premium Member Dom Jaeger Posted August 2, 2024 Premium Member Posted August 2, 2024 Looks like moisture got in there at some point. I clean and treat small corrosion spots like that with a brass wire pen brush and a product called CRC 2-26. Don’t use WD 40. 1

Oxidation on those parts is typical, they all do it. This is called galvanic corrosion. It's very common when you put brass and aluminum together. It's 100% normal, just needs to be wiped off and re-assembled. 1
Zac James Nicholson Posted August 2, 2024 Author Posted August 2, 2024 Thanks for the answers and thanks Tyler for that chemistry lesson. Glad to know it wasn't moisture which would have been a lot more troubling! 🙏 1
