Applying a silicone sealant to seal around windows or other devices requires the help of a caulking gun. Once you have completed your project, it is necessary to clean the caulking gun. When caulking silicone is left in the caulking gun or the residue is left on the caulking gun, the caulking gun might not work correctly. Remove silicone sealant from the caulking gun before it has a chance to heal completely. Although there are solvents available to clean silicone, it is not necessary when you clean directly after the project.
- Hold the top handle of the caulking gun in one hand with the tip of the tube pointing to the floor. Turn the handle clockwise with your free hand and pull the plunger backward. This disengages the piston of the caulking tube.
- Lift the caulking tube towards the back of the caulking gun with your fingers and tilt the tip of the tube away from the firearm. Remove the machine entirely and discard it.
- Wipe the caulking gun with a dry cloth, removing most of the residual caulk before it dries.
- Scrape away any caulking remaining with a knife or a 2-inch putty knife. Be sure to clean the residual silicone sealant off the peak teeth of the piston rod.
- Rub small amounts of the remaining cured silicone with your thumb. The silicone sealant will roll under the pressure of your thumb. Wipe the caulking gun with a dry cloth and store it for future use.
Tips and Warnings
- If you use solvents to clean the silicone caulking gun, follow the manufacturer’s instructions on the container for optimum results.
