Or.....Cost is simply just another positive side effect
Replace chain with clean chain, as hould be done anyway, to get some kilometers out of a drive train, using reusable quick link (yes, they've been around for ages).
Collect 3 dirty chains, dump them into the hot wax for 15 minutes, while doing something else, pick up 3 clean and well lubed chains, wipe off excess wax.
...the end.
Just getting the dirt out of a chain, genrally takes longer. If you're under the impression, that you can wash your chain like you wash your bike, try taking a link apart, and see how much grit and what not is left inside.
As for friction, any research made has shown that it's significant, but you seem to just know better, so this reply is not really for you, but rather for others who reads the thread, to weed out plain misinformation.
So TL-DR:
Yes, friction in a chain is significant, as loads of studies has shown.
Yes, you can get reuasble quick links, they're in fact rather common.
No, you can't clean a chain by washing it
Yes, xylene is super toxic
Yes, we recognize that to you money doesn't matter, so the difference between a few cents and $10 a month, is simply not worth mentioning.
If you disagree, feel free to do so, but don't clutter a thread others spend time and effort to convey information through, that's simply retarded.
For those who cares to know why I have spent some time on this topic, I'm a retired team mechanic, currently keeping some 30+ race bikes running, so I've had to spend a little time on this topic, as dealing with that many bikes, and having to deal with old fashioned lube, and the consequences of such, simply wasn't an option.
Some years I decided to dig into hot wax chain lube, as xylene is not on my list of favorites, and dry lube without doesn't work well.
I've been over testing solids like PTFE and graphite, different EP additives in pure form, and so forth.
I had the luxury of being able to compare different compositions of lube, under identical conditions, and what I have explained here, is the result thereof.
