What Is the Best Way to Get Yellow Stains Out of Fiberglass Countertops?


Quick Answer

Most stains may be removed from fiberglass surfaces with household cleaning ingredients. Items needed are: water, detergent and a soft cloth. If the stain cannot be removed using these ingredients, vinegar or an acetone nail polish remover may be used. To polish the surface afterwards, use a fiberglass polish. If the stains are minor, the counter should take about 20 minutes to clean. If the stain persists, this project may take several hours.

  1. Prepare cleaning solution

    Mix three parts water with one part household detergent or all-purpose cleaner. For a more environmentally friendly cleaning solution, make a paste out of baking soda and water.

  2. Apply solution to the stain

    With a damp cloth or sponge, wipe the solution onto the stain and scrub. Wipe off the counter when you are finished.

  3. Apply a stronger solution if the stain persists

    If the stain is not removed with the first method, apply a concentrated amount of detergent or baking soda. Keep the solution on the stain for one to two hours in order to dissolve the stain over time. As an alternative, spray vinegar on the stain, and let it sit for the same amount of time. Wipe off the solution when you are finished.

  4. Apply a stronger solution if the stain persists

    If the stain still persists, use an acetone nail polish remover or paint thinner. Use these materials in a well-ventilated area, being careful not to spill any down the drain or onto other surfaces. Place a small amount of the cleaning agent onto a clean cotton cloth, and scrub the stain until it dissolves. Use a damp cloth to wipe off the fiberglass surface when finished.

  5. Polish the counter

    Using a fiberglass polish and a soft cloth, buff the surface of the counter to fill in any scratches and to restore shine.
