Biner surface corrosion question

I recently got back from Thailand climbing in Tonsai and noticed that some of my BD wiregate quickdraws have a bit of surface corrosion. I know it's surface only as the part where the dogbone was on the biner is still nice and shiny. Not sure exactly what the corrosion is but it is a grey colour of various shades from light to almost black.

Strangely enough, of the 5 I own only 3 are affected, yet they all saw identical usage. The orange anodized biners are, of course, unaffected.

My question is, should I try to clean it, or just leave it as is? I'm pretty sure that there's no need to question the safety of the gear...

If I'd been climbing near the ocean I'd be cleaning all my gear anyway...

yes, wash them all in water, move the gates. dry. give them to me

it's aluminium oxide, and under the draws and wheer the rope runs it rubs off. Makes your hands black when you abseil

Funny that some ropes seem to make your hands more black than other ropes. I guess this has to do with how much the rope cleans the draws then.
