The only recommended way to clean your Stündenglass is with isopropyl alcohol. Gently swab the inner parts to clean. Using any other cleaners may damage the anodized finish and are to be avoided. Only the glass globes are dishwasher safe; Do Not place any other parts in a dishwasher.
Quick Clean: Remove the top globe. Rotate the unit to empty out all water. Fill with ½-1 inch of isopropyl alcohol. Thread top globe back on the device. Rotate the unit numerous times until clean. Remove top globe, drain alcohol and rinse with clean water. Remove the magnetic bowl intake adapter end cap and then the rubber plug to clean inside the valve. Removing and disassembly of the upstems may also be necessary for optimal use.
