As the title already reveals, I have a question regarding building/construction.
More precisely about outside facade/stucco and which detergents are suitable for cleaning it (since it became a bit dirty over the last 20 years) and which detergents/compounds aren't a good fit because they could be too abrasive/aggressive towards the lime in the plastering (not asking for a specific product-recommendation).
Is there a stack where such a question would be on topic?
