How to Unblock Your Foam Pump

Foam Pump

If your foam pump bottle gets clogged up, it could be due to small tiny particles that got caught on the small mesh screen within the foam pump head. Or, if you have not been using the pump frequently, liquid soap may gradually gel up and form a film on the mesh screen causing the clog as well.


Here is how you can unclog your foam pump bottle:


1. Unscrew and remove the pump head.

2. Pull hard to remove the nozzle cap.

3. Rinse the mesh screen with water.

4. Rinse the other part.

5. overturn and press the pump upwards to remove water in the air chamber.

6. Assemble back the nozzle cap.

7. Press hard until you feel a click.


You may find that when using soap nut liquid with foam pump bottle, the bottle tends to get clogged up quite easily. It is due most likely to the tiny residue in the soap nut liquid that gets stuck at the mesh screen. That is why it is important to filter soap nut liquid as fine as you can. I use a fine coffee filter paper to help me with that.


Secondly, the nature of soap nut liquid is not as smooth as liquid soap. Instead, it has more ‘friction’ in the water. This would cause friction within the pump head over a period of time and it will not bounce back as smoothly as usual. This is based on my own observation. If you love to use soap nut foam, then perhaps you might need to unclog your foam pump bottle more frequently. A possible suggestion to help with this issue is to add one or two tablespoons of liquid soap into soap nut liquid to lubricate the spring at the neck for it to work better.


If you are using diluted liquid soap with the bottle, you will find that the foam pump bottle works very well to dispense smooth creamy foam.


Sometimes, with those little bottles of liquid soap, you can buy, where you press down on the dispenser pump, and it spring returns to the up position, it may get stuck in the down position due to accumulations of dried soap. In this case, I find it usually is repairable by taking the pump out of the bottle, putting it into a container of warm water (a plugged sink, usually), and trying manually operating the pump (pull it up, rather than just rely on the spring force). Make sure the pump hasn’t accidentally been moved into the shipping position (depressed and rotated to a locked position). Operate the pump underwater a few dozen times to allow warm water to dissolve the DRIED SOAP on the outside AND inside the pump. That usually works for me with that kind of pump.
