How to scrub mortar off stones

I had my patio table "replaced" with new 12x12 slate stones and I need to scrub the mortar off it...which is everywhere. What is the best way to get all of the mortar off the stones?

I like a product called Sure Kleen but some of that mortar seems too thick to be removed without some chopping. Maybe tap it with the long side of a brick hammer.

Ok thanks. I'm guessing that can only be purchased online.

No, a local stone yard should have it.

I would use muriatic acid. Make sure to follow the directions and pay special attention to the safety precautions like good rubber gloves. I dilute the acid as instructed in a plastic bucket then use a plastic brush and the acid solution so scrub off any unwanted mortar (while wearing a full face mask, long sleeve shirt & pants and long heavy duty rubber gloves) then rinse off thoroughly with water.

I have found Sure Kleen to be better than Muriatic Acid.

I am going to pickup Sure Kleen this week. Based on photos should I stick with the Heavy Duty Concrete Cleaner or Light?

I think that you need heavy duty.
