Stupidly, I didn't realise that lawn fertiliser could stain paving, so despite brushing the paving after using fertiliser on the adjacent lawn it's still quite stained. 
The paving is an ivory sandstone and the supplier has recommended their own product; Pavtuf Rust Remover (which I note is non-acidic) but it's terribly expensive at £33 per litre.
I will (resentfully) pay this if it does the job far better than other products.
Question: Does anyone have any experience with this? Alternatives?? (Lithofin Bero or Lithofin Rust-ex)
