Advice on how to clean battery corrosion on battery coils and contacts in hard to reach small spaces? I have some solar lights that have rusty contacts and have tried alcohol on Qtips but still cannot get them clean. Thanks

I use emery boards [for filing your nails]. They can be cut to size and fit in tight places. The sandpaper scrapes the rust and corrosion off.
Thanks!

alcohol won't work. Vinegar and a q tip.
Thanks!
