I take mine COMPLETELY apart. I remove everything that is removeable. Unplug the unit. Vacuum out with shop vac, then, I wash the inside of the cabinet with mild liquid dishwash saop and hot water on a handtowel rag. My machine is stainless steel/aluminum/glass construction, so, all is well with mild (non-abrasive) detergent. Then a good damp cloth rinse. All the aluminum and stainless steel parts (except the kettle) are washing in the sink with same soap. Towel dry. The kettle gets carefull cleaning without imersing the unit in water. Reassemble and hit the glass with Windex on the outside. The doors are plexiglass, so NO windex on them. Just soap and water. Still looks new three years later.
