The answer to 'how to maintain steam cleaner' is to follow a regular maintenance routine to keep your steam cleaner in good working order. This includes emptying the water tank, cleaning the nozzles and brushes, and descaling the machine as needed.
Start by emptying the water tank after each use and wiping down the exterior of the machine. Check the nozzles and brushes for any debris or buildup, and use a soft cloth or brush to clean them. Depending on the mineral content of your water, you may also need to descale the machine every few months to prevent limescale buildup. Follow the manufacturer's instructions for descaling, which usually involves running a cleaning solution through the machine.
