Stainless steel appliances can add a clean, beautiful look to any kitchen. Polished stainless steel is merely stainless steel that has had its surface polished mechanically with an abrasive tool for an ultra-shiny look. Polished stainless steel kettles are simple to clean, but care needs to be taken to not scratch the finish.
Determine what type of stains are on your polished stainless steel kettle before selecting a cleaning product. For most dirt and grease stains, a mild detergent mixed with warm water applied using a non-abrasive sponge is sufficient. For more stubborn stains like cooked-on food, a non-abrasive cleaning powder like baking soda can be used along with mild detergent and hot water. Ensure the baking soda is completely dissolved in the water before using to prevent scratching. If the kettle is not severely stained and is just being cleaned routinely, ammonia mixed with warm water can be used instead.
Fill the kettle to the fill line with 1 part vinegar to 4 parts water, and boil. This will disinfect and deodorise the interior of the kettle while also removing scale, or mineral build-up from hard water from the kettle's interior components.
Empty out the vinegar mixture and refill the kettle with regular water, boiling again to remove any leftover vinegar taste.
Rinse off any remaining cleaner on the exterior of the kettle and apply commercial stainless steel cleaner or polish to the kettle with the soft cloth to leave a shiny, streak-free finish.
