To remove the dirt, blocking the flow of water and chemicals, follow the steps below:

  • Step 1: First, you have to put on chemical-resistant gloves since you are dealing with potentially hazardous chemicals. 
  • Step 2: Then, remove people and pets around you. Make sure you are in a dry place. Remove the entire cap of the sprayer carefully so that none of the liquid spills out.
  • Step 3: Next, rinse the sprayer cap thoroughly with clean water. 
  • Step 4: Now, use a small brush to clean out the dirt from inside the flow chambers of the tubes. If you don’t have a cleaning brush, then you can just use a thrown-away toothbrush.

Reason 2: Concentrated Chemical Components

The chemical in your sprayer can get concentrated, which can lead to the Sevin spray bottle not working. It can happen due to keeping the sprayer unclean, changes in temperature or humidity, or just leaving it untouched for too long.

Moreover, dirty or hard water can cause some of the impurities to mix with the chemical, causing a chemical reaction.


If the chemicals are concentrated, shake it well before you attempt to spray. Shaking will agitate the liquid, which allows it to unclog.

Reason 3: Insoluble Impurities

Insoluble impurities can get into the container through the water hose. This can lead to dirt building up and causing a blockage.


If the clogging is due to insoluble impurities in the chemical, you can try to filter it out. Here’s how you can do it:

  • Step 1: First, get your gloves and open the cap of the spray bottle. 
  • Step 2: Take a plastic container, like a bucket.
  • Step 3: Now, filter the chemical through a mesh filter into the bucket. If there were any insoluble impurities, they would get caught in the filter.
  • Step 4: Then pour the filtered solution back into the Sevin container.
  • Step 5: Finally, close the cap tightly and you’ll be able to use it normally.
