Neutralizing Car Battery Acid Spill: Suitable Alkaline Substances and Safety Measures

Question

Hello. For unknown reasons, the battery in the car spilled on the base on which it stands and rubber-plastic elements around. It wasn't an explosion or anything like that. As some of the acid was left in the car, how to remove it? You can already see the erosion of the sheet metal and...

Water, lots of water and more water.

acid base water and soap

In addition to rinsing with water, you can neutralize it with an ammonia solution. It has a strong smell, so if you give it in excess, you will have to air it for a long time. I advise against using caustic soda, lime because you can get burns in the event of incompetent dosing, but I recommend baking soda (the kind from the grocery store). Whatever you neutralize it will not do as the predecessors wrote without rinsing, thorough.
And with the water itself, it's a problem because you only dilute it and then what?

Well, and if he dilutes it to a concentration of 0.001%, what should he think about? If you already recommend this soda, maybe tell him to make a saturated solution and use some kind of spray. Because I can't imagine sprinkling the base of the battery and the engine compartment in general, there is too much vertical there.

Plenty of water.

Thanks for your help and tips. I will use baking soda mixed with water a lot + then super thorough rinsing with water. I think that after this treatment a wire brush + sandpaper and finally painting will do its job.

If you have any other tips, please write, each is important.

Hello . Nothing happens without a reason, in your place I would check the battery charging voltage. The battery itself should not boil over

marian159 · Answer

I support check charging, you probably have too much and the battery is boiling; Greetings

skaktus · Answer

The cause is unfortunately unknown. The battery has a charge of 14.3 volts during operation. Probably the fault lies with the battery, an unknown company and no one knows where.

JARO_17 · Answer

Of course, a solution of soda water. And as for thinning, maybe it's right that it can be almost completely rinsed, but still, I recommend neutralizing it with something mild + thorough rinsing first.

Of course you should do it ASAP. And not some kind of sprayer, just pour it normally. If you have boiled over a large part of the electrolyte, use more baking soda.

If I were you, I'd watch out for the battery now. It may be advisable to replace it with another one.

Stary1952 · Answer

With such a value of 14.3 V, which is correct, the reason is rather obvious - the battery needs to be replaced.

binges · Answer

Hello
I went through this recently too...
to neutralize the effect of the acid, I made a solution of active foam with water in a ratio of 1:1 + flower sprayer, from which a thick foam was made, it is a strong alkaline solution, so you have to be careful with plastics and varnish on the outside of the body,
I sprayed for about 3 minutes, then rinsed thoroughly with water and then repeated it 3 times (foam for 3 minutes + washing with water)

skaktus · Answer

The battery has already been put aside, interestingly, the car on it normally could give advice so unfortunately I do not know which side is the cause.

Stary1952 · Answer

One cell in the battery could be shorted, the summer period, it's warm, the starter "rotated" with 10V without any problems. The consequence of this is automatically overcharging the others combined with electrolyte leakage - this is my hypothesis, perhaps
I'm wrong.
