The wax is suspended in solvents, making it liquid for easier application

@ Peter: no longer know the link, but I understand it to be a hard wax with substances added to make it more liquid.

@ all one more thing:
The instructions for use state: "Stand container upside down for a few minutes before use". Could this be to mix the wax and sawdust that might have separated during storage? If so, this would point to the wax being somewhat liquid.
But I am aware that viscosity describes a continuum of the liquid property and glass is a liquid too. I suspect that any wax might be a liquid, some of higher viscosity than others and all of lower viscosity at higher temperatures.

@ all many thanks for your entries. The answers and comments all point to "liquid wax" which I am happy to accept.
Still, I am trying to understand ... Would this wax be liquid or solid at room temperature? To me "flüssig" and "hart" (solid) sound like a contradiction.
Or is it a wax that is hard at room temperature that was heated until liquefied, absorbed by the sawdust and then allowed to cool again and is used in that (cooled) state?
Who can explain this to me?
Thanks.

@ EdithK and Wendy Streitparth The product in question is used to clean floors, not cars.
The "sweeping powder" is from my own research, After I have seen the entries here, "sweeping compound" appears more suited.
Sorry if I have caused confusion.

liquid hard wax is used for polishing cars etc., no idea whether you also can use it for Kehrspäne or whether this is a different product.
