To use a paint tube squeezer, simply place the paint tube into the designated area of the squeezer, clamp it lightly, and then turn the crank or handle to roll the tube, which forces the paint towards the opening and allows you to extract even the last bit of paint from the tube without excessive squeezing by hand; essentially, it "wrings" the tube to get out all the paint. 

To use a paint tube squeezer effectively:

• Insert the Tube: Place the paint tube into the designated slot of the squeezer.

• Clamp Gently: Lightly secure the tube to avoid damage, especially if it's made of metal.

• Roll to Extract Paint: Turn the crank or handle to roll the tube, pushing the paint toward the opening.

• Maximize Usage: Consider using the squeezer from the start to minimize waste and maintain even paint distribution.

This method ensures you get the most out of your paint tubes with minimal effort.
