The chain with the NFS lube attracts more dirt than with wax, but since I'm cleaning my chain with the mineral spirits every ~500 miles or so anyway it's nothing for me to get concerned about. This reminds me of another reason I've given up waxing my chains for now: I had to do it more often. Under my current scheme, I clean the chain I pull off when I swap chains at around the 500-mile mark, and lube the chain I'm putting on the bike with NFS, then I'm done with my chain until it's time to swap again. When I was waxing the nice, silent waxed chain goodness would go away within a couple hundred miles or so, then I'd feel compelled to reapply. So I was waxing my chain every couple weeks or sooner (sometimes every week when I was really laying down the miles). I did it while it was a topic that interested me, but the novelty wore off at some point and I just went back to NFS. NFS is pretty awesome, btw. On a nice clean chain I'll put the 12 drops or whatever I feel like putting on, and it distributes itself nicely, just as advertised. My chains run nice, smooth, and silent for the whole 500 miles until I swap chains.

I haven't mountain biked in several years. When I start mountain biking again I may well go another route, possibly revisiting waxing. I just don't pick up enough actual dirt on my road bike chains to be worth thinking about.

ETA: I used the heated ultrasonic cleaner instead of a crock pot because I happened to already own the ultrasonic cleaner, and it worked. At least it worked up until it broke. Then it didn't work anymore. I could go out and buy a cheap crock pot at Goodwill or something, but since I'm off waxing for now at least I haven't bothered. I do miss the ultrasonic cleaner though. It was useful beyond just cleaning/waxing my chains.
