Clean the area using the solution and a brush. It doesn't have to be a steel bristle one, just one which is stiff enough to remove the gunk. You will have to remove the battery cables to get them completely clean sorry about the radio channel presets!
Finish your clean up with a good dose of water to flush the area of any residual corrosion. If you don't, it can eat away the paint in the nearby areas.
When done cleaning, to help slow down the corrosion process, coat the terminals with grease high pressure grease or wheel bearing grease works as good as anything.

You can also purchase a aerosol spray coating which you can purchase from your local parts store. Your main objective is to keep the lead, escaped hydrogen gas, and oxygen from mixing which forms the corrosion you see after a period of time.
Over time the grease will break down and corrosion may start, so regular cleaning and reapplication is a must. If you do this about every six months, you should be in good shape. Much of the corrosion is due to bimetal contact between copper and lead alloys.
Nothing to do with Hydrogen. While the battery does produce hydrogen gas The corrosion is probably due to lead sulfate. The metals on the terminal post and connecting fitting are to close by design in galvanic similarities to be an issue.
After some significant testing I now have a better solution than what I originally accepted. Use the auto store battery felt pads along with the grease for a long-term, lasting solution. If grease can be used in battery terminal , why a petroleum jelly is supplied with battery and as per technical installation, supplier directs to use petroleum jelly not a grease. I encourage car owners no to apply grease on car battery terminals rather to apply petroleum jelly.

Use battery terminal protectors also known anti-corrosion pads on each battery post, preferably one that is saturated in a battery corrosion preventative compound. Reconnect the battery cables but in reverse order from Step 1.
In other words, reconnect the positive battery cable first, and the negative battery cable last. Use a battery corrosion preventative spray or brush-on compound, and provide a generous coating on the battery posts on the battery and battery terminals of the battery cable. Privacy Policy.
