> Degrease your bicycle chain with kerosene or some other solvent, and submerge it in molten paraffin for 20 minutes.
Clean it with isopropyl alcohol after degreasing it and before submerging in the paraffin.
After a few hundred kilometers you'll need to submerge it again. Boil a kettle of water and use it to clean the chain before submerging it in the paraffin.
Some people suggest adding PTFE to the paraffin, but I have no idea whether it has any benefit.
I used to use the paraffin wax method, but I added micronized graphite rather than PTFE. It works well, but does make the wax look dirty. Nowadays, I find it too much faff to bother with the hot wax soaking and I just use commercial wax/dry lubes as I was ending up "topping up" the soaked wax chain with that anyway. I found that wax needed re-applying every 100-150km.
