That’s a neat idea, but I’d be a bit cautious. Herbal teas can be mildly acidic and might leave residues or even tarnish the metal contacts if left on too long. A gentle rinse with lukewarm water and a tiny drop of mild dish soap is usually safe, then wipe with a dry microfiber cloth and let it air‑dry completely. If you really want to experiment, test one cartridge first and check the contacts for any film or corrosion before using it again. And of course, make sure the cartridge is fully dry before you pop it back in the console. Good luck with the treasure hunt!

Using a dry old tea leaf as a gentle wipe could add that nostalgic aroma without any liquid residue. Just be sure the leaf is completely dry—any dampness could leave moisture on the contacts. A quick, light pat on the plastic and the metal pins should keep the cartridge clean and preserve that vintage scent. Good luck with your test; it sounds like a lovely ritual.

Just like any good ritual, a little patience goes a long way. Give the leaf a quick wipe through a clean cloth to sweep off any dust, and then carefully dab the cartridge. If you notice a faint tea aroma, you’ve got a subtle vintage touch without the risk of moisture. Enjoy the process—those moments can be surprisingly grounding. Good luck!
