How often should you clean your faucet aerators?
Grumpty's answer
Every 6 months
Why bother
Scale chokes the screen, and lead can collect in it. A thorough-tier job. Skippable when life's busy, worth it when it isn't.
Why it's a range
Water is the whole story. Hard water furs the screen up fast, so a kitchen tap on a hard supply wants a look monthly. Soft water and a quiet bathroom tap will go the full six months and then some. Twice a year suits most homes.
What the job involves
- Cover the drain so nothing small disappears, then unscrew the aerator off the faucet tip by hand, counterclockwise. If it's seized, grip it with pliers padded in masking tape or a rubber jar-opener.
- Take it apart over your hand, noting the order of the screen, washer, and any discs. Snap a photo so reassembly isn't a guessing game, then pick off the loose grit.
- Soak the parts in white vinegar to dissolve the scale. Twenty to thirty minutes for a light fur, a few hours or overnight if the hard water's caked it on.
- Scrub with an old toothbrush, poke any blocked holes clear with a toothpick, rinse it all, put it back in order, and screw it on. Run the tap and check the flow.
Do it yourself, or pay someone?
Yourself. Fifteen to forty-five minutes at the sink with white vinegar, an old toothbrush, and maybe padded pliers. No plumber. If it's too corroded or clogged to clean, don't keep soaking a lost cause, swap in a new one. A replacement aerator runs about $3 to $8 and screws on by hand in minutes.
Signs it's overdue
- Weak, reduced, or steadily dropping water pressure at that one tap
- An uneven, splashing, or spitting stream, or a hiss or whistle from the faucet
- Visible mineral crust, grit, or discoloration in or around the aerator screen
When to start thinking about it
A few days' warning does it. Grumpty grumbles 2 days out, then leaves you alone. Mark it done and Grumpty sets the next one, every 6 months, so you can go back to forgetting it exists.
Questions people ask
How often should the aerators get cleaned?
About every six months for most homes. EPA-aligned health-department guidance (Michigan, Rhode Island, Health Canada) and the home guides like This Old House and Bob Vila all land on at least twice a year. Do it more often, as often as monthly, if you've got hard water, a hard-worked kitchen tap, or water-main work or pipe work going on near the house.
Why bother at all?
Two reasons. The screen catches scale and grit that throttle the flow and make the stream spit and splash. The bigger one: EPA and state and provincial health agencies note that sediment, debris, and lead particles collect in the aerator, so an uncleaned screen can shed lead into water you drink. A clean clears both.
Clean it or just replace it?
Clean first. Unscrew it, soak the parts in white vinegar, scrub, reassemble. If it's badly corroded or won't unclog, replace it. A new aerator is only about $3 to $8 and goes on by hand in minutes. Some health guidance also suggests replacing drinking-water aerators roughly once a year regardless.
