There is no one chemical to clean all paving slabs, much depends on the mineral/colouring content of each slab.
Remember to test first on a small area

Try these: Lemon Juice -  let it soak in for 5 mins then scrub with brush and then wash off with clean water, or you could use white vinegar (spirit vinegar) in the same way.

As a last resort - Oxalic Acid is good on concrete or stone, im not sure on using it paving slabs, but its very toxic, so use with caution! ;)

 wet the surface then apply brick acid ( from builders merchant ) pressure wash with turbo lance. repeat till staining is gone. be carefull not to over do the turbo you might damage the surface. take care with the acid too.
