So to summarize: I recommend you do NOT soak your bearing guided router
bits in Simple Green as it will negatively affect the bearings.

Simple Green is fine for cleaning router bits. But, Simple Green is a
degreaser. As was suggested, you need to replace the lubrication that you've
flushed out.

Flushing the lubrication isn't the problem - that's a given when you soak
something in degreaser. You just have to replace the lubrication. Which,
btw, is probably what you want to do. Lubrication embedded with wood dust
isn't much of a lubricant.
