Cement removed from windows

Today Spick & Span cleaned the windows in  a  2 bedroom split level flat overlooking Brockwell Park in Herne Hill. The windows had not been cleaned in all the time that the current occupants have lived at the property.The flat was  situated in the middle and top floors, which made  accessing the windows difficult. Builders had recently carried out work outside of the property and many panes of glass had been splashed with cement which needed removing, this Spick and Span were able  to do by using abrasive scouring pads.
