How to Give Luster to Fiberglass Sinks

Ashley Friedman

Years of use, wear and tear can leave fiberglass sinks dull and covered with soap scum and residue. Often simply washing your fiberglass sink with soap and water can superficially clean the surface and get rid of visible stains.

However the combination of soap and water alone often isn't enough to revive the original shine. Fortunately, there are ways that you can both clean your sink effectively and use some commercial products to to restore your fiberglass sink's original shine.

  1. Rinse the sink surface in warm water.

  2. Apply the dish washing soap or the baking soda to a soft cloth that has been dipped in warm water.

  3. Scrub the surface of the sink with the cloth, moving the cloth in a circular motion.

  4. Clean around the rim of the sink with a sharp-edged tool to scrape out any dirt or debris stuck there.

  5. Rinse the sink thoroughly with warm water, making sure that the surface feels smooth and that no residue remains.

  6. Dry the sink with a soft, clean cloth.

  7. Apply Gel-Gloss, or other shine agent, to a clean cloth.

  8. Rub the cloth over the sink surface and allow it to dry; it will have a hazy sheen.

  9. Using a clean cloth, polish the Gel-Gloss off, revealing the shiny surface of the sink.

  10. Tip

    It is not recommended to use a harsh, abrasive surface cleanser on fiberglass as it can scratch the sink's surface and dull the sheen. However, if stains are not coming up using baking soda or dish washing detergent, an abrasive cleanser may be necessary.
