Yep, exactly. The clamps will most often have rust on their bottoms. If it wipes off, good. Use a soft brush and get the corresponding deposits off the bellows too. If the clamp's pitted (even lightly), replace and use that clamp for a less critical area or save as a spare. Again, if you clean the area well and use a corrosion inhibitor, you'll get indefinite use from the clamps. Another example: I just pulled eight 10" exhaust clamps while I was working close by. I know it's been a year. Still only a couple showed superficial corrosion; they were previously sprayed with inhibitor.

Having had a trip delayed for two days in '17 because of a coolant clamp letting go, no clamps go anywhere on Aslan unless they get a shot of corrosion inhibitor. It's no trouble once the routine is established.
