The OP did not answer my question as to whether he knew how to use a search

Googling "rubber protectant" brings up over one million responses. Here's
one...

By the way, the thing that protects a lens is a called a lens hood or lens
shade. Other than generic models, they are no longer made of rubber.

So that is what the OP was talking about, I figured if it was a lens
hood he would have know enough to call it that.

Only if what I am talking about has a lens anywhere near it.
Darn, I guess my eye counts. My hat is now a lens hood! Or is that
lens hoodie? lol
