I just happened to look at the positive post today. It is covered with a red plastic cover. When I unsnapped this cover, it was full of greenish corrosion. Baking soda and water took it all off. I could not believe how much corrosion there was. I have a photo it, but do not know how to upload photos. Just check yours out. My 09 TL is 19 mos old.

Good idea to keep those terminals clean!

Use coke. It works great. Usually if there is a work party I will take a leftover 1/4 bottle that would have been thrown out and use it.

Yes you need to stay on top of that issue. As soon as I got the car home the first thing I did and do with all my cars is put some SuperLube grease on the terminals to prevent corrosion. And if all else fails just use some vaseline. Works just as good.

Vaseline, really? Wouldn't it be too prone to the heat from the engine melting it away? Not during the winter, but.....

What you need is any type of dielectric grease.

There are also some type of felt pads that go over the posts to help prevent corrosion. Being that you are in Seattle (close to the Ocean) you are going to have more corrosion issues than some one who isn't coastal.

You would be suprised how well it works when/if your in a pinch. But that is why I suggested the Superlube.

I never heard of using Coke either!

Vaseline will work. I used it on my previous Maxima. However, any thick type grease will work.

Pour some Coke into a glass, drop a nail it, let it sit for a few weeks and have a look

Are you still having issues with your battery terminal getting corroded?

I have had this issue off & on now the corrosion seems to have seeped all the way throughout my power cable going to the starter. I even bought a Tsunami gold plated terminal and it's still corroding.

NO , sprayed dielectric grease on it and its ok. You can always get the felt washers you can get at an auto parts store to place on the terminal. They work good for me on my other car and in past cars.

4 TBSP Baking soda and 1 1/2 cup of water mixed up - drizzle it on there, will clean it right up. Need some compound on there to keep the corrosion down; any autoparts store or even department store should have a small can or tube of anti-corrosion solution/goop, and some terminal insulators that are saturated with it if you choose to use them.

Are you near the ocean or something? Odd to be that corroded.

I live in a suburban city east of Seattle. Don't think ocean is a factor. I used baking soda to clean the stuff off. Anyone reading this thread should look underneath their positive terminal cover. You would be surprised by what you find. If you don't have any corrosion etc, than that is good. My wife's vehicle also had the same stuff under the terminal cover.

Unless you've got cells leaking, moisture is always the biggest culprit. Anti-seizing/corrosive barrier on there and you should be fine.
