Indian sandstone patio


I have recently had a raj green indian sandstone patio layed for me which looks great. But unfortunately it has some cement stains on I would like to remove before it gets Sealed. I have been told brick acid is a big no no with sandstone. What would you recommend for it?

Hi probably best way to do this is get high pressure jet wash and a hard bristle brush to remove cement stains make sure not to blow out joints with jet wash .

Cheers again.

Correct to not use brick acid on sandstone, as sandstone is quite a soft and porous stone which the acid could leave pits or further damage to the stone. A heavy jet wash or steam clean could get the cement stains off depending on how bad they are/how much cement is left on the stone, or try patio/driveway cleaner or maybe sugar soap.
Hope this is of help to you,

A wire brush and carefully jet wash but beware as the cheaper softer sandstone may splinter!
