Won't grease cause the "rubber" to deteriorate?

That depends on what the "rubber" is and what the grease is.
O-rings can be natural rubber, silicone rubber, nitrile etc.
Ditto the grease - silicone, petroleum-based, vegetable-based
etc.

I've always used wheel bearing grease. It may be the wrong thing to do but
I've not had a problem with it yet on o-rings and gaskets.
