Maybe don't use it. Using anything like degeaser around hubs and BBs can eat out the grease in the bearings and if they get rusty, may seize up. I made a very expensive error once by regularly degreasing my chain on the bike. I was using one of those fancy chain cleaner devices, and the fluid still got into my rear hub and eventually the bearings seized the wheel.
Sadly just trying to let lube run into your hubs and BB is next to impossible. You will have to undo them (if loose bearings) and do it properly.
