Yep. Works well for me.
I don't use a chain cleaning device. Dunking the chain in degreaser apparently doesn't do it any favours either, it strips the factory lube out. See KMC service advice
and CTC's chain Q&A page
I use a toothbrush and a small amount of citrus degreaser briefly to remove the grime before washing it off with water. Once the chain is dry I apply Green Oil by putting a drop on a toothbrush and brushing along the chain to work it in between the links. I rub it lightly with a cloth to remove excess - too much on the outside means it attracts more dirt.
This usually lasts for a couple of weeks of daily commuting or sometimes longer before it starts getting a bit noisy. The Green Oil seems to continue to work when the outside of the chain is getting a bit dry.
GT85 is a reasonable substitute in dry weather and/or if you don't do many miles. WD40 is a dispersant and has no real lubricating properties. I wouldn't recommend using it as a chain lube.
Don't put any lube on the cassette, it doesn't need any.
