Hi,

We have some Indian sand stone to clean in a beer garden. What's the best product to bring it back looking like new?

Thanks

high pressure water that should do the job
should be all it needs

My book keeper did her Indian Sandstone patio with just OxyKlenza, a hose, watering can and a broom.

 Indian sandstone is not suited for our climate. Really it needs sealing as it is very porous. BBQ areas generally suffer from fat and red wine stains.Shaded areas suffer from sap and algae staining. First treat any problem areas. A pressure washer and a flat surface cleaner is then  used ....as little pressure as possible so not to damage the substrate.

Sandstone requires no pressure whatsoever to clean.

Pre wet the stone until flooded
apply a high alkaline cleaner and scrub it in with rotary scrubber and soft nylon brush
allow to dwell then scrub again and vacuum off
Then rinse and vac again

Chris don't want to get into a big debate but to say Indian Sandstone is not suited to our climate is a bit misleading, yes it is porous it just needs a bit of TLC  it is still most probably the most common natural stone that home owners go for patios etc. With regards to damage to the substrate I agree you don't need pressure just the right chemical, dewell time and I bit of common sense when cleaning sandstone or any natural stone for that matter. Even sealing needs topping up every 18 months when using a impregnating sealer.
