Re: Does Ballistol dissolve phosphor bronze washers?

Just found this great thread—thanks for the input. I’m wondering if you ever tried leaving a drop of Ballistol on the washer for a longer time? And whether that greenish lint on Endura washers would appear with other lubes too? I’m still unsure after all this time.
A few years ago, I used Ballistol to wipe down Spyderco blades (never on washers—used KPL), but stopped after reading about its potential to tarnish or dissolve copper and worrying it might reach the pivot area. Since then, I’ve used mineral oil, Tuf-Glide, or EDCi instead.
Recently cleaned patina off a washerless Stretch XL with Ballistol—worked great, but as I let it sit on the blade for some time it penetrated deep, even into the lock area behind the liners. I also planned to revive Micarta PM2 scales with Ballistol after a year in dry storage.
I'm still wondering—could Ballistol fumes tarnish the washers of other knives if stored in the same case as the Stretch XL I used it on, or if I apply it to Micarta or G10? It penetrates deeply and doesn’t dry quickly.
I also remember an old video where the author felt that Ballistol slightly etched the surface after a week-long soak
