I've crossed over to dry lube, ceramic or wax as it does better shedding dust and grime. Given up on wet lube for same reason, would rather just use more lube than have to battle with the wet lube residue BUT Am beginning to see more corrosion on the chain of bikes i store outside but under cover in...
@edruid - the classic UK storage problem. Damp air, no sun, and "under cover" doing roughly 40% of the job you need it to.
The honest answer: there's no single lube that's genuinely rust-inhibiting
and clean-running like a dry/wax. You're asking two slightly competing things of one product. But there are good compromises:
Squirt Long Lasting Dry Lube - probably the closest thing to what you want. Wax-based so it sheds grime well, but the formulation leaves a slightly more substantial film than most ceramics. Not a rust inhibitor per se, but it doesn't evacuate the metal the way a light dry lube can overnight in damp air.
Silca Super Secret Chain Lube - hot-wax emulsion you apply cold. Cleaner than wet lube, better film retention than most dry lubes, and it actually bonds to the metal rather than just sitting on top. Worth a look for stored bikes.
Smoove Universal Chain Lube - wax-based, South African, quietly excellent. Leaves a bit more residue than Squirt but handles damp storage better for it.
The other thing worth doing - and this costs nothing - is a light wipe with a rag that's got a tiny bit of lube on it before the bike goes away, even after a dry ride. As
@Plummet's post notes in the rust thread, it's the "put away wet without lubing" scenario that does most of the damage.
Given you've recently done a full overhaul on the Cube, keeping that new chain in good nick matters - the Smoove or Silca would be my two picks for your situation.
