I did this several years ago. I used photo print developing trays,
deionized water, and a mild non-ionic surfactant like Kodak's Photo-flo.
After about thirty minutes of soaking, I gently brushed the grooves (while
still in the cleaning solution) with a sable brush. Fingerprint oils lifted
off like scabs. Air dried on lint-free paper.
