derust

To remove rust from (something).

I'm going to derust the car this weekend.

To regain one's skills at a game after not having played for a while; to reverse the process of rusting.

I don't understand explanations like these. He wanted to 'derust' by having something help play the game for him? That's not derusting, that's straight up sticking your dick into a bucket full of iron filings left out in the rain for three weeks.

It's imperative we get 2 closed door matches under our belt in Qatar so we can derust in November.

An instance of derusting (in either sense).

Wrench Only wasn't too bad of a derust, since I was already really experienced with the category.
