Perfect care / basic cleaning

The Franke Putzstein is only recommended, although he does not clean so much limescale (which I removed beforehand with descaler or dilute acetic acid), but he cleans the sink of fat and other dirt deposits that are otherwise not so much look at granite sinks.

I scrub my sink every one to two months thoroughly with the enclosed sponge, after thorough washing the sink has a slight lotus effect, water "pulls" to the draining properly together. After cleaning the sink but you have to wash very well, so no white residue left behind. I rub the sink then once properly dried, then it looks like new.

Whether the cleaning at the granite sinks from the hardware store also works so well, I can not say here, however, since they are made of a different material.

Can only be recommended.
