Thanks for showing the better rinsing approach, which is to use the acid-neutralizing baking soda. Also, it's helpful to know in advance that the bolts take a 10mm socket -- thanks for mentioning that.
Glad it was helpful! The cleaning solution was something my dad taught me more than 35 years ago!
Try not have a continuous water path between terminals that allows electrical current to flow.
That’s true. It can sometimes be observed with light bubbling when the current heats up the water around the terminals. However, the battery dries off pretty quickly. I’ve never had an issue in 30+ years of washing engines and cleaning batteries.
Nice video. Only caveat is to know what is under that battery and maybe protect your driveway. I had a AAA tech do this to the battery terminals on one of my cars - he used a pump sprayer. Replaced the battery and the car started fine. Next day the car wouldn't start. Turns out the starter was directly underneath the battery and it had gotten caked with the baking soda mixture. That destroyed the starter and also left a large stain on my driveway.
Oh man! I’m sorry to hear that! Did they make it right?
This happens because the seal around the post is leaking. I always put a bead of silicone around the post where it meets the case best if done when new.
Yes, that can be one reason (and a good solution too). Also, all batteries have vents to release hydrogen gas when the battery charge is cycling, which can cause terminal corrosion. Another cause of corrosion is if you have copper terminals. When they get wet, that will cause a reaction with the lead posts.
I would never let my engine bay stay that dirty good fix though.
I recommend hot water it’s worked better and faster 😊
The pressure washer at a car wash also does a great job too!
A lot of slurry was created by the baking soda and water mix and it overflowed the battery tray a bit. I rinsed with fresh water inside the engine compartment area that it dripped into. Is this an issue?
Great question! No, it will not be an issue. It’s always a good practice to get the solution and dissolved acid rinsed out, but a small amount of the solution residue will not be a problem.
What kind of grease?
It can be regular grease that you would use for bearings or you can use dielectric grease (more expensive). The point is to seal the connection off from oxygen and prevent the chemical reaction that produces corrosion.

If it works, go for it!
I hope a pro wouldn't clean a battery like that. I take a shop vac, suck up any loose corrosion after removing the cables, take the battery out, submerge the battery terminals in the baking soda/water solution in a plastic container then use a rag dipped in baking soda/water solution to clean the top of the battery. You're inviting problems just pouring the solution over the battery while it's still in the vehicle.
