Cleaning cement grout from sandstone patio

Hi there we've had a shoddy landscape gardener lay an indian stone patio and the grouting is now all over the slabs. Ive read acid cleaners are a definite NO and ive heard about sandblasting...

Anyone have any ideas as it looks terrible.

Thanks in advance

Kantor acid brick cleaner down and a high pressure jet wash that will solve the problem

Hi with it being Indian sandstone I would suggest either a stiff brush with some warm soapy water or a clean water jet wash I would not put any chemicals or acids on this type of patio hope this helps.
