Here it is in gruesome detail (thank your lucky stars I didn't think to photograph each stage):
- Photograph chain while still on bike from various angles so I know how to put it back.
- Diagram the chain around the various cogs and sprockets for safety
- Since I was advised to put the chain on backwards afterwards, I used a couple of cable ties to try to keep track of the orientation (who knows if I did or not)
- Use a master chain link to undo the chain and remove it
- Place chain in a small tub with orange/citrus based degreaser
- Remove rear wheel
- Clean chain rings at front (where the pedals are) with the degreaser and old rags
- Clean cassette (9 gear sprockets) on rear wheel with the degreaser and old rags
- Stir up the tub with the chain so the degreaser gets its work done
- Rinse off the chain rings and cassette with a hose pipe - leave to dry
- Use hot soapy water to clean off chain, followed by several rinses - leave to dry
- Use spray degreaser (Amorall) on derailleur (rear gear change mechanism) and clean with paper towels
- Use WD40 to spray out sand or grit from derailleur
- Lube the derailleur
- Replace rear wheel
- Study photos and diagrams of how chain needs to be reattached
- Put chain back in appropriate orientation (I think)
- Lube each link in the chain
Now I wonder if I shouldn't have just taken the bike in to the shop and asked them to do this. Maybe next year.
PS: Yes, I helped with the Passover cleaning, too!
