Cleaning 12V connectors (like car battery terminals trailer connectors or RV connections) is important to prevent voltage drop and electrical issues. Here's a safe method: First DISCONNECT THE POWER - for car batteries disconnect the negative terminal first then positive. You'll need: a wrench baking soda water a stiff brush (old toothbrush works) wire brush and electrical contact cleaner.

1) Make a paste of baking soda and water (about 3:1 ratio). 2) Apply it to the corroded terminals - it'll fizz as it neutralizes acid corrosion. 3) Scrub with the stiff brush. 4) For stubborn corrosion use a dedicated battery terminal brush or fine sandpaper. 5) Rinse with clean water and dry completely. 6) Spray with electrical contact cleaner (like CRC or WD-40 Specialist) to remove any remaining residue. 7) Once dry apply a thin layer of dielectric grease to prevent future corrosion before reconnecting. Reconnect positive first then negative. This process works for any 12V connection - just be thorough with drying since water and electricity don't mix! This video tutorial shows the process clearly.
