The stain removing “magic” of club soda works part of the time for part of the stains. It never works on grease or oil. Greasy stains look absorbed and have no “ring.” Never use club soda on fine fabrics like silks. The dyes may bleed and run. Splashing club soda on wine, coffee or colored sodas will loosen and dilute the stain. Blot – never rub – to prevent the stain from bleeding into surrounding areas. And bring the garment to us as soon as possible.
