How to clean the foam gun thoroughly?

Common practice:

First take the gun blowing agent from the gun, and then clean the interface with cleaning agent, and then install the bottle cleaning agent through the interface, and then pull the trigger several times to spray cleaning agent, until the muzzle spray liquid almost no color, take off the cleaning agent, so far, the cleaning process is over.

So is this thoroughly cleaned?

In fact, it is not. Maybe you are confused that you have cleaned the foaming agent gun every time you have used it, but a new gun is used only a few times, and there are always different degrees of blockage, and even affect the quality and progress of the construction. This can only show that our cleaning is not thorough enough.

As we know, in the use of foaming agent gun, caulk will constantly deposit in the gun chamber, and over time, gradually hardening and "strong" attached to the wall of the pipe, with such stubbornness, only a few seconds or tens of seconds of flushing, it is not completely cleaned.

So how do we do that?

Instead, you can: After installing the bottle cleaning agent on it, first pull the trigger a few times, clean most of the caulk in the gun chamber, and then let the cleaning agent soak in the gun chamber for a period of time (how long is the specific time, five or six minutes is absolutely done), and finally, pull the trigger a few times, the residual caulk in the gun chamber is washed clean, so that the foaming agent gun is cleaned quite thoroughly.
