I decided it would ultimately be less expensive to wax and rotate through 3 or 4 chains repeatedly until everything is very obviously totally worn out, and then replace the whole of the drive train (or at least the set of chains and cassette). If the new chain skips on the front ring, you will know you have over-done it, and can replace that. So far, it has only cost me an inner-chainring ($10) once, and I am replacing cassettes far less frequently.

I use several chains in a rotation. When I clean a chain in naphtha, I let it dry for a day, then apply some lube with the chain hanging vertically from the middle and drizzling it down from the top. I make a second application, when the chain is installed on my bike. I relube about every 150 miles or once a week and take the chain off for cleaning and to exchange for a different chain about once a month.

For what it's worth, Steven from OZ Cycle has made great videos on chain waxing on his YT channel. He also made on the lifespan of a waxed chain VS a non-waxed one and the duration between each waxxxxxxx session.
He uses 10 parts paraffin & 1 part PTFE mix and it seems to work like a charm. No other additive are used.

Oz has other videos on chain waxing with plain paraffin. He claims that it's the PTFE that makes the huge improvement. He's not very knowledgeable when it comes to solvents. He tried making a liquid paraffin lube with isopropyl alcohol, which is very wrong. He adds lamp oil to paraffin too, but that's really just a very slow drying solvent.
I'm a mechanical engineer, not a chemist, but I did prove that naphtha will dissolve paraffin at room temperature and remain a liquid, but if too little naphtha is used, it turns into a mush instead of a water-like fluid at temperatures under about 75 degrees. My lube needs to warmed by placing the applicator bottle in hot water for awhile, unless the room temp is high. In a cool room, the chain may also need to be warmed or the lube may solidify before penetrating adequately.

Naptha will dissolve paraffin wax, but the ratio of wax to naphtha is no good for a lubricant. The naphtha evaporates and leaves behind an insufficient amount of wax to lube anything.
Th reason he adds paraffin oil is to soften the wax so it doesn't just shatter and crumble off of the metal parts when they flex. It acts more like a loose grease with paraffin oil added to it. Steve talks about it while he uses a knife to arrive at the correct balance of oil/paroffin.
I have been waxing chains for a few years now. I did the ptfe mix for a while but now just do the wax and paraffin oil in a 1 quart crock pot.
For A while I even stopped cleaning them before dropping them in the wax but that just ruins the wax prematurely. Now I shake them in naphtha or mineral spirits. Then purple degreaser, rinse in water, and into the wax. I get about a season from a chain, 5k miles roughly speaking.
I do the wax thing because my bikes come into the house. And a dirty greasy, oily, filth covered chain just wouldn't work out well.
