How to prevent terminal corrosion?

[crharvel]

With all the problems that can be caused by deteriorating connections at the battery, what have folks found to be the best at slowing/preventing corrosion?

Di-electric grease

You can buy this stuff in a can at autozone that you can spray on your battery terminals to pretect them. I've used it and it works good.

what about the fuse box, I noticed some corrosion starting already. Has anyone tried or knows of a spray I could use if I pull out all the fuses.

I found some spray contact cleaner at home depo, pulled all my fuses sprayed the fusebox with the contact cleaner. used 500grit sandpaper on the fuses, a little di-eletric grease and put it all back together. I hate the way that stupid battery cover snaps on, fell down a few times while driving so I removed one of the mounts and now zip-tie the sucker, I found some reuseable zipties while I was buying the contact cleaner.

All my motor vehicle owning life I have just used WD40 or similar products and have NEVER have one spot of corrosion on battery terminals.

Give 'em a quick spray 2 or 3 times a year and they're good.
