In my experience the drip on wax is enough. I put new chain in acetone, then alcohol (each bath about a day), just in mason jar nothing fancy.
After installation I apply drip on wax, which lasts about 100-150 km (it is based on really soft paraffin so doesn’t last long).
I think so I used it only on fresh device, but in Linux file system personal data and app data are separated.
