The stone on my house which I think is Bath stone or Limestone is getting dirty. I’m not sure if it’s pollution, acid rain or something else.
I tried to give it a quick scrub with water and a gentle soap but I didn’t have any luck.
Can anyone tell me the type of cleaning agents that might be able to help or if this needs something more extensive?

I have no experience of cleaning this stone, but I do recommend caution using any products you might find yourself.
Cleaning this type of stone is a likely to be specialist job, especially on a historic building. There is a risk of damaging the face of the stone and any work you carry out might be restricted by local regulations for listed buildings, conservation areas etc.
