Whats the best way to clean benchtop granite in the kitchen?

Are there any stains on it?

Updated the question Two birds with one stone

The best way, recommended to me by a fitter (granite, not epileptic) is soapy warm water. (Fairy liquid)
Wipe down the surfaces (including the stove) with the soapy water and then dry with a tea towel. It works brilliantly.
We used to use glass cleaner, but it didn't work as well and apparantly damages the surface.

This is what I've done with mine for about fifteen years but I was scared stiff that if I said so, there might an outcry of "how unhygienic, how minimalistic, haven't you oldies ever heard of bacteria...?" Didn't want to start my new year with a guilty conscience.

Well the Granite has stains from calk. I used a granite polish but its alot of work. I use sometimes dish washing liquid but not sure if it damages the granite

Turps worked on mine.

In one of our places in London, we had a company come in and re-finish the surfaces of the worktops. I guess after a while this is probably needed and then you can start anew.

This is what I use to clean our benchtop granite and glaskeramik kochfeld. Its from the Migros.

Hi,

There are hard water stains near the sink of our kitchen on the granite floor. I'm looking for a suitable and strong cleaning formula/liquid to remove them. If found this on Amazon but somehow it didn't work :/ (Maybe I didn't use it correctly): https://www.amazon.de/dp/B008VBC0YO

Does anyone have a recommendation here? Something that worked for you?

Much appreciated
Thanks

Vinegar. That's good with calc.
