There are quite a few things wrong with this faucet.
There is a lot of dried up minerals that make it impossible to rotate the faucet. If rotated, the faucet rotates at the base instead of the mid section. The mechanism seems jammed. How do I clean this part so it rotates smoothly once again?
The base used to have some sealant which came off so I used some soft silicon gel to seal it at the base. As you can see the it has separated from the faucet's metal base but is still adhered to the granite (?). What is the right product to seal this properly?
In an effort to fix #1, I have tried going under the sink and tightening the bolt but no matter how much I tighten it, the whole faucet seems to move mainly due to the aforementioned mechanism being jammed.
Do I need to bite the bullet and replace the faucet or is this fixable?
We seem to live in an area where water is excessively hard (320PPM) so I am guessing this will recur. Is there a way to prevent it?
