Fuses corroding in Blue Sea box

I've got a Blue Sea fusebox on my boat and the blade fuses seem to corrode quite badly.I'm using normal car blade type fuses. It's not a sealed box-but it's in my console and hasn't got wet so it's got to be salty air thats doing it.

Are any others available that won't pit and turn to fur?

Try smearing silicone grease on them before fitting.

I use it on all electrical connections on the boat and it seems to help keep the water out.

You can get it at loads of places including Maplin who do a spray version. They also have a contact cleaner which might help if you already have 'fuzz' there.

Try also buying some electrolytic grease, supposed to stop this very problem and available from online car accessory merchants for around a pound or two.
I have put this on all my fuses this time round, its not the Blue sea fuse panel thats at fault as car fuses corrode due to dissimiliar metals in contact with each other with electricity flowing through them.
I am waiting to see in a year or two whether the grease has worked but at a quid or two its worth a go.

Good tip, cheers.

I know it's not the box at fault and about dissimilar metals. I was wondering if someone made stainless fuses or would this facilitate corrosion on both the fuse and the contact?

Glass fuses seem much better but they all need a good greasing!!!
