Spyderco Sharpmaker

[flphotog]

I've got a Spyderco Sharpmaker and love it. I do have a question about the diamond rods. I don't use them very often but do now and then. I cleaned them once some time ago with soap and water like I do the ceramic rods but afterwards noticed some rust on them so have been hesitant to do that again.
Is there an accepted way to clean the diamond rods without them rusting?

I typically just pat them (DMT hones) dry with a paper towel after cleaning... no rusting issues thus far.

Thanks, but that thread didn't really answer my question, it just added a few more. I've contacted Spyderco and will post their answer here if and when I receive one.

More than likely, the rust is embedded swarf left from previous sharpening sessions, and not the rods themselves rusting; they're coated in nickel, which doesn't rust. Rusting swarf is fairly common to see on diamond hones, if they don't get fully cleaned & dried regularly. Swarf gets embedded on the surface, and it usually takes some scrubbing to dislodge it.

Use some Comet/Ajax cleanser and water, with a stiff brush to scrub it; this is the commonly recommended method by makers of diamond hones, like DMT. Can also use some Barkeepers Friend cleanser in the same manner. The BKF uses oxalic acid, which will dissolve any steel swarf left over; makes it much more effective (it's GREAT for cleaning up rust, BTW). Make sure to rinse the hones thoroughly after doing so (HOT water will evaporate more quickly, BTW). Lightly dousing or blotting the rods or other diamond hones with isopropyl alcohol after cleaning & rinsing will displace any remaining moisture on the surface, so they dry completely and quickly.

I use BKF with a blue Scotchbrite on my Spyderco rods and DMT stones.
