My 2 cents worth .........
I've sold chain, sprockets, bearings etc for years for a living.
Chain manufacturers told me:
1. Take the chain off the bike
2. Completely submerge the chain in diesel overnight.
3. Dirt etc will 'fall out' and settle in the bottom of the tray.
4. You can give it a scrub with a hard toothbrush or parts wash brush as well to get out the tough crap.
5. You don't need to completely wash away the diesel afterwards. A blast with an air compressor or a fresh flush with diesel will do.
6. The diesel will not harm the o'rings if it's an o'ring chain.
- Almost all chain o'rings, regardless of brand or price, are generally made of Nitrile (acrylonitrile-butadiene rubber or Buna-N).
- Nitrile is completely compatible with diesel in both static and dynamic applications
7. The diesel will also act as a lubricant and will not be effected by, or effect, your chosen chain lubricant.
8. Dry off with a rag (so you don't drip diesel everywhere) before refitting to the bike.
I've done this on dirt bikes and road bikes for 20+ years. My chains have always lasted very well.
A chain that's in good condition will most certainly help with the longevity of the sprockets.
EDIT: I've never sold Supercheap degreaser but the other brands I've sold such as CRC, Chemz, Wynns etc are all compatible with Nitrile o'rings
The diesel is an idea I'll have to check out.
Just to add one more thing... one of the worst things that you can do is nothing. A mate did exactly that with his bike. The lubricant inside the O-rings eventually ran out, the O-rings themselves started to crack, and then one of the O-rings broke and dropped out. The chain then had a sideways offset between two links. This wore itself in and got worse. Pretty rapidly it got to the point where the chain was going to bind up around the sprocket and run off, or break. Or jam completely and lock the back wheel.
New chain, drive sprocket, wheel sprocket... it wasn't cheap!!

Cup of kero, brush and a rag. Apply kero sparingly, by the time you've done a full lap of the chain it'll be damn near done. Wipe off the cruddy stuff with rag. Repeat if necessary. Apply chain lube in modest fashion, wipe off excess.
To avoid anyone treating you like a noob, save the water blaster suggestion for the garden path. Water blasters and road bikes don't get on well...
Arguably this is one of your better counterpoints. But alas, you still miss the actual point. A water wash off degreaser is what comes off, before the lube (see, for your information, its water repellent properties) goes on, see 'the order of the steps in the bloody post' for supplementary information previously overlooked.
It's like how it's a bad idea to ride your bike around halfway through a tyre change; fucking self explanatory I would have thought![]()

Clean Rag soaked in kero - clean (bike on stand, NOT running). Clean, dry with another clean rag. Oil with suitable shit. Job done.




Or as I've seen done by someone who shall remain nameless....back racebike up to fence around pits. Put it on the stand and fire it up. While idling in gear apply chain lube generously, avoiding losing a finger but watching the crowd gather outside the fence...Then rev the tits off it, in gear, spraying excess lube over the suddenly abusive crowd....Shit, does the back tyre grow when you do that.....
A guy at high school munted several fingers lubing his chain with the bike on the main stand and in gear ........
I have found this thread to be informative, entertaining and very funny. 8/10

The Supercheap degreaser that I have in the shed smells very like diesel anyway. And its not very good degreaser.
it's not a bad thing till you throw a KLR into the mix.
those cheap ass bitches can do anything with ductape.
