How To Apply Vaseline To Your Battery Terminals

Applying Vaseline to your battery terminals couldn’t be simpler! Just follow the steps below!

Prepare A Mix Of Baking Soda And Water

First, mix up a paste of baking soda and water. That’s right- we said baking soda! The mixture should have an almost paste-like consistency to it. Once you’ve got the perfect ratio of ingredients, you can start applying the concoction to the battery terminals.

Remove The Cables From The Terminals

Before putting the paste on, make sure you disconnect the cables from the terminals. Don’t use any metal tools that could spark or cause a short circuit- just use your hands and be gentle while doing this.

Check For Corrosion

Now, take a look at the terminals and see if there’s any corrosion. If you notice any corrosion, then move on to the next step.

Use A Wire Brush & Baking Soda Paste To Remove Corrosion

Once you’ve identified any corrosion, take your wire brush and the baking soda paste and start scrubbing away at the affected area. This should help loosen any build-up that could be causing problems with the battery terminals.

Dry The Terminals Thoroughly

Now that you’ve removed any corrosion, use a clean and dry cloth to wipe down the terminals. Make sure there isn’t any baking soda paste left behind.

Add Vaseline To The Terminals

Finally, put a layer of Vaseline on the terminals. This will help seal them up and keep any moisture from getting in and causing further damage. Plus- your battery will look shiny and new!

Reconnect The Cables

Now that you’ve got your battery all fixed up with Vaseline, it’s time to reconnect the cables. Make sure they’re tightly secured and that you don’t have any loose connections. With this final step, your battery should be in tip-top shape!

And there you have it- a few simple steps for how to put Vaseline on your battery terminals!

Your engine should start right up, and your car’s electrical system will be grateful for the added protection from corrosion. And remember, Vaseline can also come in handy for circuit breakers, light sockets, and other electrical components.
