OP-if you can, try working the Lederbalsam in with your bare hands. The warmth of your hands will help the conditioner penetrate into the leather. I would then leave it on overnight and wipe it off in the morning.
If the leather really needs it, sometimes I will then do a second conditioning.
It's funny, I actually prefer the Passier Lederbalsam because the leather feels more supple to me than the Effax. I really think it is a personal thing, though.
