Need to clean up a travertine wetroom, it's not in too bad a state, but
it's had some heavy use recently whilst our main bathroom has been
reffitted.

Our local tile shop sells some very overpriced branded cleaners, but I
figure there must be generics I can buy?

From what I can gather, it needs to be Alkaline.

Looking at this:

Any other suggestions?
Thanks.
