Cans can clog as well , the way to clean them is to get a bamboo scewer and gently push the tip in to the valve (Note this is for Female cans for male cans just push the valve down with out the cap on it and it should clean out the clogged paint) the paint will spray out so, direct the spray on to old news paper or some thing , if its the cap , for acrylics soak in metho if its for enamels soak in white spirts, (white spirits will work also on acrylic laqures )
