Kitchen faucet spraying sideways? Try this before calling a plumber

The water no longer comes out in a neat stream. Instead, it sprays sideways, splutters, or runs more slowly than it used to. You might assume the water pressure has dropped or that your kitchen faucet is wearing out.

But the problem is often much smaller. At the end of most faucets sits a part. Over time, limescale and tiny particles of dirt can collect inside it, making the water spray in all directions.

Fortunately, cleaning it is usually a straightforward job. However, there's one popular cleaning ingredient that some faucet manufacturers specifically warn against using on the finish.

What is the tiny mesh inside your faucet?

The aerator is a small fitting attached to the end of the spout. It mixes air into the water, creating a smoother stream while reducing splashing. Many aerators also limit water consumption, which can help save energy when using hot water.

Limescale and debris can gradually restrict water flow or distort the spray pattern. This is especially common in areas with hard water, where dissolved minerals leave deposits on plumbing fixtures.

If only one faucet has started spraying unevenly while the others work normally, checking the aerator is a sensible first step.

How to clean your faucet aerator

You don't normally need special cleaning products. Before starting, place a towel over the sink drain so you don't lose any small pieces.

1. Unscrew the aerator. Turn the fitting at the end of the faucet counterclockwise when viewed from below. Use a soft cloth for protection or the correct aerator key if necessary.
2. Rinse the mesh. Hold the insert under running water to remove loose particles and grit.
3. Soak the removable parts. Follow the cleaning instructions for your particular faucet.
4. Rinse and reassemble. Make sure the rubber washer is correctly positioned, then screw the aerator back on by hand without overtightening.

Experts recommend soaking removable aerator parts in vinegar for approximately 15 minutes. Alternatively, it suggests dissolving half a tablespoon of citric acid powder in 100 ml (about 3.4 fluid ounces) of warm water.

Sometimes you may need a longer, 30-minute white vinegar soak for heavy deposits.

The cleaning time therefore depends on the buildup and the manufacturer's instructions.

Why some faucet manufacturers warn against vinegar

Vinegar is a popular household descaler, but that doesn't mean you should soak the entire faucet in it.

Some advise against household vinegar, acidic cleaning products, and abrasive sponges because they can damage the surface and leave it looking dull or scratched.

Similarly, advise against vinegar-based cleaners, is coupled with recommendations to use a mild citric-acid-based product applied to a soft cotton cloth rather than sprayed directly onto the faucet. Removable aerators can also be soaked in warm water with a suitable cleaning agent for around ten minutes.

The important difference is between cleaning the removable insert and exposing the faucet's decorative finish to chemicals. Always check your particular model's care instructions, especially with matte black, brushed, brass, or gold-colored finishes.

What if the aerator won't unscrew?

Some aerators are recessed and require a special key. Others may be difficult to remove because of mineral deposits.

Avoid forcing them with bare metal pliers, which can scratch the finish.

Although some household tips recommend wrapping a vinegar-soaked cloth around the faucet tip overnight, this can expose the finish to acid for hours. It's safer to avoid that method unless the manufacturer explicitly permits it.

If the aerator is stuck, consult the faucet's manual or ask a plumber for help.

How often should you clean it?

There's no fixed schedule for every household. The cleaning frequency depends largely on water hardness.

In hard-water areas, inspecting the aerator every couple of months is a reasonable habit. You may need to clean it sooner if the stream becomes uneven.

Wiping the faucet dry after use also helps prevent visible mineral deposits.

And if cleaning the aerator doesn't restore normal flow, the problem may lie elsewhere, such as the faucet cartridge, supply valve, or household plumbing.

Either way, checking that little mesh first could save you an unnecessary plumbing bill.
