I have used it often for contacts. Just recently I bought a package of 4 used remotes on eBay. Three would not work because the battery terminals were corroded. A quick spray with WD40 and now 4 out of 4 work like new.
Forget the grease stuff. Over the last 20 years or so the only thing that ALWAYS works is WD40.
