If left unaddressed for long enough, it may even cause your battery to prematurely fail.

Before cleaning your battery, see your SL550 owner's manual to learn how to disconnect the battery cables. After disconnecting the cables, use a mixture of water and baking soda, a wire brush, and a rag to carefully clean the terminals.
