It also accelerates the process of rust and corrosion.

This is a simple fix. Find something absorbent to place inside the fob. A tissue or paper towel will be ideal. Then apply a cotton swab dipped in isopropyl alcohol and wipe down the circuit board and other components to clean out any battery acid residue and contamination.
