I took the chain off, removed the rear wheel.
Cleaned the front cogs in situ with an Evans special brush and citrus degreaser, then gently rinsed. This took a while.
Leaned the rear wheel at an angle over a bowl and cleaned the cogs with the Evans brush then gently rinsed off. This also took a while.
An alternative would be to take off the outer and middle front rings and dunk them in cleaning fluid, and take the rear cluster off and dunk that.
The second option looks like less effort in that the components can be soaked, and potentially vibrated in a cleaning bath, making the cleaning easier and removing the issue of getting cleaning fluid on the bike and the wheel in places it shouldn't be.
I am, however, wary of little unexpected extra things which pop up when you don't use the simplest method.
I’ve never used fancy oil on my chain or any other part of the bike. For a long time standard 3 in 1 served my needs well for literally thousands of miles. Now any oil that’s in the workshop for say a mower is a fine general purpose lubricant, IMHO it’s a bike not some finely tuned high performance rocket vehicle.
Any downside to a partial strip down for cleaning?
Yes there is a downside to partial strip down for cleaning. It takes ages and it risks disturbing things that might not go back together as intended (bits get damaged, parts get lost and somethings just get put back together incorrectly).
My day to day ride is a hub gear bike and one of the reasons for that is the ease of maintenance, however I have derailleur bikes too and recently dusted them off plus cleaned the transmission up. I use the thin blade of a wall paper / paint scrapper tool (eg. https://www.amazon.co.uk/Amtech-G0665-2 ... Cdiy%2C180 ) to move hard muck off of the chainwheels and between the rear sprockets followed up with rags. Turn the cranks, position scraper and off comes the bulk of the crud. The chain is cleaned with oil and rag, sometimes an old paint brush comes in handy too to brush off and poke out crud. The jockey wheels might need removing and greasing, I didn’t bother last time but I should have done - probably best to do one jockey wheel at a time.
Though I aim to it isn’t actually necessary to remove every last bit of grime and crud, just try to keep things oiled and the working/wearing surfaces of parts clean.
