My builder has managed to splash quite a bit of limewash on my brick garden walls. Any tips on getting this off? It will have fully carbonated by now.
My basic chemistry would suggest something acidic. A dilute solution of Spirits of Salt perhaps? (Calcium Carbonate + HCl --> Calcium Chloride + CO2 + H2O).
