You could try to put some diluted calcium remover ( in Canada we use a product called CLR) (after you clean the little white filter tip using the same tecnique) Turn the device on to draw the solution into the heat chamber, let it heat up, and let it sit a while. Return a few times to reheat up to hot and give it some good shakes. This might loosen up the calcium inside. (You should be using distilled water in the steamer at all times to try to minimize mineral buildup) Try shaking and steaming upside down to try to get some of the loosened sediment to spritz out (dont get burned) Rinse with clean water. Do this outside so the evil vapours don't demineralize your lungs. Good luck
