And as far as the chains go, the treatment is applied to the metal and doesn’t “wash out” once you’ve cleaned the chain (think of it like Teflon coating on a frying pan). It does however give certain waxes a hard time adhering if you’re doing that stuff. That said my DA chain has no problems with Silca Super Secret, and I think their Synergetic is fine with it too (that’s the one they recommend for gravely dirty stuff)
