Steps

1

Unscrew the aerator

The little screen at the tip of the faucet — twist counterclockwise. Wrap the threads in a cloth so pliers don't scratch.
2

Soak in vinegar

Let it sit in a cup of white vinegar for 15 minutes. Scrub the mesh with a toothbrush.
3

Reinstall and test

Hand-tighten the aerator back on. Pressure should be back. If not, the cartridge inside the faucet body may be partially clogged.
