Hi all - just wondering if anyone has any experience with or knows what would be good to use to remove some rust marks I've got on one of the paving slabs on my patio.
It doesn't look like surface rust so not sure simply power-washing will do anything! (however I am going to try!)
If it makes any difference it is Kandla Grey Indian Sandstone - bit wary of using any kind of brick acid type product as I know this can royally mess them up. There are a few recommendations on here http://www.pavingexpert.com/stains.htm but nothing that directly relates to sandstone so didn't want to lob loads of vinegar or lemon juice on it and it end up wrecking it!
I am going to give it a power wash anyway this weekend but wanted to give the stain a seeing too if possible with some kind of cleaning solution, whether that is something like Jeyes or Patio Magic or plain old washing up liquid, or something a bit more specialist!
Any help is appreciated
