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!
Worked beautifully. First try. Cleaned off seven years or corrosion build up in about seventeen seconds. Now i can actually see the terminals again so i can replace the battery!
thanks! im gonna try this on my feet!!
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.
Thank you for making this video
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?
People don't do this... You never pour water or water + baking soda solution directly on the battery like this. You take the battery out, use a cloth/paper towel with the solution and make sure you don't get any water/baking soda inside the battery. A lot of batteries have 1 or two raised spots with covers on them on the top where you can actually get liquids inside the battery if you do it the wrong way like in the video. You have to be more careful with it. You can EASILY destroy your car battery doing it like OP did in the video.
OP says he's a pro but is doing this, and also didn't take out the battery to make sure there was no corrosion underneath the terminals.
Great Vid! Would you put the grease over both terminals or just the negative one?
I recommend hot water it’s worked better and faster 😊
The pressure washer at a car wash also does a great job too!
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.
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.
Does it have to be fresh?
can i use baking powder
What kind of grease.
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.
I would never let my engine bay stay that dirty good fix though.
I don’t disagree, but we also live in a rural area with lots of dirt and sand roads. It’s impossible to drive it and stay clean. 🤷🏻♂️😅
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.
I spent many years as a pro, did everything in a pro way, and charged people pro prices. At the same time, I’ve been cleaning corroded batteries in my personal vehicles using this method for 40 years without a single issue (my dad did it this way many decades before teaching me). This channel is focused on helping DYIers fix their cars and save lots of $$$ using tried and tested methods. Thanks for visiting.
Cleaning the battery while it’s on the vehicle won’t do a damn thing. You don’t know Jack.
I usually poor a can of coke on it. Cleans it right off.
You think tht works better than baking soda ?
@@jackboy2472 Nah it does the same thing except that soda leaves a sticky residue and attracts ants
Coke Cola pop 🥤
If it works, go for it!
