Anyone had experience of cleaning/renovating these?
I have used a Karchi water-blaster on (horizontal) sandstone paving with excellent results - any reason why I couldn't use it on stone window sills/lintels/surrounds? (On cottage mainly built from random limestone/slate).
If not, what's the best way to get them looking smart (apart from sandblasting, or painting them)? They have just got a bit dirty and tired-looking over time.
Thanks in advance.
