I realize this is 5 years old, but I just had to create an account to address this. Yes, the electrolyte can, CAN, be dangerous. It is no more inherently dangerous than say, bleach. You just need to wear good safety goggles, not glasses. Keep the garden hose close and a preopened box of baking soda close. Buy the premixed electrolyte at an auto parts store. Read the directions on the box to use it. Move slowly and deliberately. If you do spill some on your skin just flush it with the garden hose for a few [minutes.it](http://minutes.it) is not something to fear, just respect. This nanny state mentality that everything is scary, dangerous and bad for you is removing many things used in repairs, projects and whatever from availability. Can some of the products be used for nefarious reasons, yeah, they can. Take powdered aluminum as an example. Yes, it can be used to make things that go BOOM. But it is also in thermite. Can bad things happen with thermite, yup, really bad things. Can you weld with it, they do it on a daily basis. I’m trying to do a successful iron casting with it, has not gone well yet. I believe that with the right procedures and some more practice I’ll get it right. A homemade cast iron part without needing a huge cupola furnace is the cats meow for me. I use safety gear, it’s like 5 or 6 thousand degrees F. ``` Buy electrolyte and use it safely,it's easy and works just like it's supposed to. ``` Don’t be afraid to try new things. There is danger lurking everywhere. Don’t be a pu\*\*y. Prey soon all we’ll be able to buy is milk and eggs. Not flour because you can make flour bombs. Milk and vinegar makes a kind of plastic, should we ban vinegar because it too is an acid. Rant over. Have a great safe day everyone. --- _[View the full topic](https://community.cartalk.com/t/adding-sulfuric-acid-to-a-car-battery/72582)._
