'and you get mortar on it you're buggered etc'

Can you explain why??

LTP have a new 'black stone' product out. I will try and dig out the documentation to see what it says

LTP Blackstone - https://www.ltp-online.co.uk/prod/ltp-blackstone

More of a sealer restorer. Will still need a deep clean first.

I had this problem, didn't read into the problem of black limestone before filling in the cracks with Mortar.

I have managed to removed 90% of the stains by a combination of Karcher and scrubbing with a little bit of 'pink stuff' cleaner. Then applied LTP external stone sealer (water based).

Hope that helps.
