Hold a clean, soft cloth under running water to saturate it. Remove the cloth from the water and squeeze it gently so that it's damp -- not dripping.
Wipe the surface of your Formica furniture with the damp cloth once a week to remove dust. Apply a mild soap and water solution if needed. Allow the furniture to air-dry.
Sprinkle baking soda on the Formica surface if you have tough stains. Scrub with a damp, nonabrasive sponge to remove the stains. Rinse with water, and wipe dry.
