Back in the '70s- pre Stein tool- I was told that the only proper way to lube a freewheel was disassembly and regreasing. Being the lazy and cheap sod I am, I instead just used cheap automotive motor oil (decent chain lube too!) squirted into the gap and let gravity and a little spinning of the wheel to work it in. Sometimes I'd even use (gasps) spray lube- this was considered at the time a sure fire FW killer. I don't recommend any of this, but you know what? It seemed to work, and still does 30 years later.
