Cleaning the limescale spots from the outside of a stainless steel kettle is a 2 minute job with Vistal Multi Surface Cleaner and it leaves the kettle looking like new again.
A lot of the limescale can be just wiped away with a microfibre cloth, but there is always a residual amount which is stuck to the kettle (see first picture below). This isn't surprising because the water drops that run down the kettle after you have poured some water evaporate off quickly because the kettle is very hot, leaving hard limescale on the surface.
The process with Vistal Multi Surface Cleaner is as follows:- Dampen the sponge and wipe across the product and squeeze to get foam. Rub the surface of the stainless steel until the limescale spots have gone. Wipe away the white residue from the kettle with a damp cloth. Finally buff lightly with a dry cloth.
Vistal leaves a microscopic layer of glycerine on the surface which gives a very even, streak-free shine. Go to the Vistal online shop.
