Here is a tip that helped me retain flavor and remove some of the build up you get with a standard atomizer . Get your atomizer hot hold the button down for about 7 seconds . Remove the atomizer and blow through the atomizer from the drip tip into a paper towel . This should lighten the draw and remove some of the sediment build up . There is a mesh on the bottom of the atomizer that clogs up after a couple days of use .When I was using standard atomizers I would remove this mesh and my atomizers never clogged
