The answer to 'why is my steam cleaner greasy' is that a greasy steam cleaner is often caused by a buildup of dirt, grime, and residue from the cleaning process. This can happen if the steam cleaner is not properly maintained and cleaned after each use.
Some common symptoms of a greasy steam cleaner include leaving behind a greasy or oily film on surfaces, poor cleaning performance, and a musty or unpleasant odor coming from the machine. To fix this, you'll need to thoroughly clean and descale the steam cleaner according to the manufacturer's instructions.
