I wondered why my fanheater kept melting sockets. First I blamed the

Why don't you replace all your plugs with gold plated mains plugs like

Then replace all your mains sockets with these

Although not quite as good conductivity as silver, at least the gold
ones won't have oxide buildup.

Sounds a bit overkill, I'll just make sure high current devices get polished if the prongs aren't shiny.
