How to clean spray nozzles

Clean your spray nozzles in 8 easy steps:

Did you know that a worn or clogged spray nozzle can increase liquid consumption by 15–20% without being immediately noticeable? Reduced spray performance leads to wasted chemicals, inconsistent product quality, and higher operating costs. Fortunately, regular inspection and cleaning can prevent these issues. Spray nozzles should be cleaned regularly for an optimized performance and lifespan. Thousands of euros can be saved annually by regularly maintaining your spray nozzles and replacing them in time.
 

1: Prepare the necessary materials

You will need warm water, a small bowl or container, mild dish soap or a suitable cleaning solution, a soft brush or toothbrush, and a clean cloth. Always remember to use a non-corrosion cleaning agent.

2:Remove the nozzle

If possible, detach the spray nozzle from the bottle or sprayer. This will allow for easier cleaning and ensure that the nozzle is thoroughly cleaned.

3: Rinse with warm water: 

Hold the nozzle under warm running water to remove any excess residue or debris. This initial rinse helps to loosen any clogs or build-up.

4: Soak in 

Prepare a mixture of warm water and mild dish soap or a suitable cleaning solution in a small bowl or container. Place the nozzle in the solution and let it soak for about 10-15 minutes. This will help break down any stubborn residue.

5: Scrub the nozzle 

After soaking, take a soft brush or toothbrush and gently scrub the nozzle. Never use a metal object to clean a spray nozzle and always use a material which is softer than the nozzle material. Pay close attention to the openings and crevices, ensuring that any residue or blockage is removed. Be careful not to use excessive force, as it may damage the nozzle.

6: Rinse thorough

Rinse the nozzle under warm water to remove the cleaning solution and any loosened debris. Ensure that all the soap or cleaning solution is thoroughly rinsed off.

7: Dry the nozzle

Use a clean cloth to pat dry the nozzle or let it air dry before reattaching it to the spray bottle or sprayer. Make sure it is completely dry before reassembling.

8: Test the nozzle

Once dry, reattach the nozzle to the bottle or sprayer and test it by spraying some water or the intended liquid. Ensure that the nozzle is functioning properly and there are no remaining blockages.

Should you clean or replace a rusty spray nozzle?


The spray nozzle on the photo to the right is full of rust and clogged up. It is possible to clean it and see if it can function properly, but in most cases we would recommend to replace it at this point.

Rust is often a sign that the nozzle material has deteriorated, which can affect spray performance and reliability. If corrosion has affected the nozzle orifice, spray tip, or sealing surfaces, cleaning will not restore its original performance. In these cases, replacing the nozzle is the best solution.

Should you clean or replace a spray nozzle with streak?

Streak means that there is an area on from the spray nozzle orifice where no liquid in being sprayed, often resulting in dripping and uneven liquid distribution.
This can be caused by several factors such as clogging, wear or damage. If you have a spray nozzle with streak, we recommend that you first check it for damages around the orifice. If the main problem seems to be clogging, you can still try to clean it. If the The spray pattern still remains streaked after cleaning, you should replace it. If this problem often occurs, you should look for a more wear and clog resistant spray nozzle. 

When should you replace your spray nozzles?

01Poor spray pattern:

If you notice that the spray pattern is uneven, inconsistent, or has become distorted, it may indicate wear or damage to the nozzle. This can affect the efficiency and effectiveness of the spray.

02Clogging or blockage:

If the nozzle frequently clogs or gets blocked, even after thorough cleaning, it could be a sign of nozzle deterioration. Over time, nozzles can develop internal deposits or corrosion that impede proper flow.

03Leaking or dripping

If the nozzle is leaking or dripping even when not in use, it could indicate a worn-out seal or damage to the nozzle. This can result in wasted product and reduced spraying accuracy.

04Physical damage

Check the nozzle for any visible signs of damage such as cracks, breaks, or significant wear. Physical damage can affect the spray pattern, flow, and overall performance of the nozzle.

05Excessive wear and tear:

With regular use, spray nozzles can wear down over time. If you notice significant wear, such as flattened or deformed spray orifices, it may be an indication that the nozzle needs to be replaced.

06Reduced performance

If you observe a significant decrease in spray distance, coverage, or overall performance compared to when the nozzle was new, it may be time for a replacement.

Looking for a more sustainable solution?

Ceramic nozzles have a longer lifespan

For demanding industrial applications, ceramic spray nozzles offer significantly greater durability than conventional metal nozzles.

Benefits include:

  • Exceptional wear resistance
  • Longer service life
  • Excellent chemical resistance
  • High temperature resistance
  • Increased rigidity
  • Reduced maintenance and replacement frequency

Do you frequently experience clogged spray nozzles?

If you spend a lot of time cleaning your spray nozzles, you may want to check if you can replace it by a more clogging free version or one with a wider free-passage diameter. Read our guide on anti-clog spray nozzles:
