Been waxing for a few years. I did a diy mix loosely based on the Friction facts recipe, my PTFE powder was not good quality and clumps, but the overall mix seems to work. GF had a box of little tea light candles she didn’t need so wax was free.
Just got a pot for a buck from goodwill and my wax lives in that, had a hot plate so the overall setup costs were little. Although the wax drips on the hotplate can make the first minutes of fondue night a little stinky…
Up until my last batch I Was doing mineral spirits in a jar for cleaning but have switched to a cheap HF (free, my parents ended up with 2) ultrasonic cleaner with some citrus degreaser and water mix. It doesn’t fit a cassette so I have to run it a few times turning it, but hey it was free. Ultra sonic cleaner seemed to do a great job of cleaning of any old wax, didn’t expect it, but I also preheat the chain in a spare toaster oven which melts off any remaining wax, little stinkier but easier than the boiling water method.
I don’t do the GFs chain or my gravel/cx bike chain, maybe one day but for now rock n roll gold. For my race (tri) bike I rotate 3 chains, 2 training and 1 race. I’ll throw the race chain on for 1 outside ride before a race to work it all in and usually forget to swap it off for a handful of trainer rides after. The other two chains usually go about 300 trainer “miles” before they start to get a little bit of chatter and swap them out.
I’ll use a fresh link when the race chain goes on, then that link gets recycled with each training chain swap.
Since I rotate 3 chains after I install the second trainer chain and need to redo the first I usually will then clean and wax the race chain, put it in a ziplock ready for the next race this way spending time waxing a chain race week doesn’t add any stress, it is just ready to go.
