Someone "polished" my varnished mahogany dining table with teak oil. How do I remove it?
If the table was varnished, then the applied oil will not have penetrated and could be removed with a rag soaked in mineral spirits. Don't use more volatile solvents as they could soften or damage your varnish. Afterwards, wipe clean with a separate damp cloth to remove all traces of the oil and spirits.
