Having gone through this thread there are lots of useful tips. I have been waxing chains for a long time and here is a bit of extra data that may help some:
- Don’t take your chain out of the wax, when the wax is still totally clear. At this stage it is still too hot and much of the wax will drip out of the rollers before it cools down.
You can actually leave your chain in the wax until it starts to get a skin on it, even longer.
The only “downside” is that there will be lots of wax still on the chain and you simply pull your chain through your fingers and let the lumps of drying wax fall back into your pot.
Doing it this way almost doubles the length of time before rewaxing.
- If you just use pure candle wax etc. you need to add some lamp oil/parafin oil into the wax when it melts. This stops the wax from being too brittle. (Pure candle wax is not correct). Add about 25% parafin oil to 75% candle wax.
To get an even closer ratio, you can add the blade of a cold blunt knife into the wax/parafin oil mixture and pull the knife out again. The wax will harden on the knife. It sound be a slightly firm cream consistency, not flaky.
Far, far cheaper than using Molten Speedwax and at least as good.
- I use a camping stove and an old steel pot to heat up the wax. Only takes 5 minutes to melt about a kg of wax. Don’t bother messing with crock pots and timer pots.
When the wax is melted, take it off the camping stove and turn it off. Put in your cleaned chain and stir it around for a minute or so or until any little bubbles disappear. The leave it for 10 to 15 minutes to cool down. Then as it gets cloudy or a thin skin form on the wax surface, you can take the chain out.
- If you really want to clean a chain “perfectly” then you need to soak the chain in a small jar of petrol.
The petrol literally dissolves the oil or any old wax still on the chain.
Obviously never do this indoors or anywhere near a naked flame or cigarette etc.
Leave it soaking for 10 or 20 minutes and swerl it around and bingo, the chain is cleaned.
Hang up the chain to let the petrol evaporate off.
You can reuse the petrol 5 or 6 times at least. You can even pour the petrol through a metal sieve at the end to clean it a bit.
If you want to also clean the chain further, then you can also degrease the chain and then rinse off with water to get rid of any smell.
You can also further soak it in vodka or alcohol and then hang it up to evaporate off. This makes absolutely sure that no water is left inside the chain.
Once a chain is fully cleaned and using the above methods, it literally takes 30 minutes to wax 4 or 5 chains for different bikes etc.
You can even do the above to your rear cassettes which will make eveything waxed, and last even longer.
I mainly started doing this for improved drivechain efficiencies for my TT bikes, but now I do it for everything.
Having a waxed chain means no more oil on hands or car when transporting or when swapping out wheels or fixing punctures etc.
