I have a portable garage & left the hood closed, but not latched the 1st time I used my battery tender.
I mention portable garage because as you know, it is not moisture free like a real enclosed garage.

I noticed this week that slight oxidation has set in, or on my alternator bracket & alternator.

Is there some spray that I can use that 'eats' away the oxidation?

Car is only 5 months old so it's not crusty & set in.

Thanks

I think you'll want to be really careful about getting anything inside the alternator.

Ours has 4 yrs/55k miles and is not nearly that bad, but I leave it alone because I'm afraid of damaging the insides of the alternator. There's probably a safe way to do this, but I haven't researched it yet.

We've been using the CTEK tender that plugs into the cig lighter, for about a year. No additional corrosion in that time.

Get an old sponge, cut it into little pieces. Stuff the little pieces in the vent holes of the alternator, and use one of the ideas above. The idea of the sponge is keeping the products off the copper winding of the alt so you don't damage the varnish.

I'l try these suggestions this week, thanks.
