Most rides just a clean off with muc-off (or equivalent, spray that on the sponge and give the chain a few rotations), then re-lube with squirt. I’d give it a blast with the pink fenwicks every few rides in winter with the clamp on chain cleaner also, then the sponge.
my fenwicks sponge is impregnateed with black grease now-I saw on a video somewhere that they can be cleaned
I use magic fairy shampoo which works extremely well for cleaning anything from cassettes to chains and sponges too. Just don’t get it into your bearings unless you intend to regrease them afterwards! 🙂
