A surface cleaner serves an all-purpose role in the home and can be used to clean many surfaces: kitchen and bathroom cupboards, the inside of the fridge/freezer, kitchen and bathroom surfaces, carpet accidents (the vinegar cleaner is best for this use), and some appliances.
Gently shake the spray bottle before spraying the cleaner on the desired surface. Spray the cleaner and wipe off the surface with a damp cloth (this is important when using the castile soap cleaner since it can leave a soapy residue if left to dry)! Do NOT use the vinegar cleaner on marble or granite. The castile soap (avoid the citrus variety) cleaner may be used on sealed marble or granite.
