Wheelbuilding / Wheel Building / Wheel build help

Oven Pride, plastic takeaway box or large glass jar, long rubber gloves and a mildly abrasive pad like a kitchen scourer...
Disassemble, clean, degrease & rinse the part you're working on, pour the OP over the hub shell (doesn't need to be submerged, just coated), leave a couple of mins, give hub a rub with the pad to help etch the surface and accelerate remaining removal, put it back and repeat as necessary until the surface of the part is a dull grey (the OP coating the surface of the hub will uniformly turn a soapy white colour). Then rinse clean and maybe submerge in a weak acidic solution (water + white vinegar) to neutralise any leftover OP. Should take 5-10 mins depending on how good the ano was.
Then, fine steel wool or a Scotchbrite pad, some metal polish and a rag to polish. A cordless drill also makes DIY 'hand' polishing much faster/easier, if you're able to lock the hub shell to the drill chuck with a dummy axle.
Once polished, some hubs tarnish or corrode more readily than others (depends on alloy), but as Mack offered a factory polished option, yours will prob be fine.
EDIT: If you're stingy like me, you can pour the OP back into the bottle for later re-use. It loses some viscosity but still works well enough for stripping ano.
