Whats the best product for getting rust of paving? Stains left from barrell type flower pots just got circles of rust which I couldnt remove. Lee has told me Tensid do a product but just want any other suggestions or any tips?
Paving is flag stones but old and really weathered.

Cheap option is soak then apply well diluted Hydrochloric Acid, this will take the rust almost immeddiately so rinse after about 20 seconds. Repeat as required, increase strength as required. I'd start about 4 part water.
Tesid will be Safety Clean. Great product, a genuine acid alternative. Use in the same way but less likely to damage anything.
Tensid offer samples, might be just enough for waht you need then try both.
