Name the substance and approximate time of the spill where known. Explain blotting, rubbing or products applied afterwards and any colour or texture change. A close photograph and a wider furniture view help show the mark and its position. Avoid adding further unfamiliar products or repeatedly scrubbing while suitable treatment is being considered.
Some stains may improve without disappearing completely, and missing colour or damaged fabric will not be repaired by further cleaning. If pets were involved, explain recurrence and smell separately, including concerns about filling beyond the visible patch. Keep realistic expectations with the actual incident and material rather than relying on a complete-removal promise.
