I've got some textured (non slip) vinyl flooring in the workshop (I
think it's Rhino flooring)

Now, it is VERY hard wearing but I just can't get it clean. In the
doorway I have a doormat and when this is lifted the flooring looks like
new.

I want to return the rest of the floor as close to this if possible.
I've tried many domestic vinyl floor cleaning products but NONE gets the
dirt and grime off to my satisfaction.

Does anyone know of a product that will get this vinyl flooring clean?
either used neat or diluted?
Depends what might have been put down on it before. I tried steam
cleaning the vinyl floor in my kitchen, but it had a floor polish
(John Lewis I think) used on it for years. It all just turned into a
sticky mess, which took me ages to clear off by hand. The floor still
doesn't look clean.
I'll be interested to see if this thread leads to anything.
