What do you think about liquid dishwasher soap?
For that "april fresh" feeling while sailing?
Actually, and you guys will laugh, KY jelly is the best thing to use for loading bearings into (non-captive) traveler cars. It's thicker than liquid soap but still water soluble to wash away clean. If you're ever in my toolkit and see that tube of KY in there, fret not - it's for the bearings!
