Low flow at a kitchen faucet: what’s the safest way to clean the aerator?
If a low-flow kitchen faucet has an aerator that might be clogged, should the faucet’s supply stops be closed before removing it, or is turning the faucet off enough? I’d also like to avoid scratching the finish or putting the aerator back together in a way that changes the spray pattern.
Would weak flow at both hot and cold settings make the aerator more likely, while a problem on just one side point elsewhere? And if the aerator has small parts or a specific orientation, what’s a sensible way to keep track of them during cleaning?

Turning the faucet handles off is generally enough; closing the supply stops is an optional extra precaution, not usually necessary to remove an aerator. If you use a tool, protect the finish with a cloth and avoid overtightening when reinstalling. Keep any parts in the order they come off, noting their orientation so you can put them back the same way.
Weak flow on both hot and cold makes a shared restriction at the aerator more plausible. If only one setting is weak, the issue is more likely along that side’s supply or faucet path. Those are clues, not proof, since other shared or side-specific restrictions can cause similar symptoms.
