What chemical to use to clean this?

Hi there!

I have to quote a costumer to cleand this stones, thy’re dirty from mopping the floor basically. And a big problem is the stones are next to the elevator so using a lot of water is a no go.

What chemicals should i use to clean this?


That looks like faux stone to me, so basically printed concrete. Beware.

It’s quartz tiles. Those are smaller stones glued to a net, that net is attach to the wall with tile mortar
