How to Care for and Clean Your Fiberglass Sink

Fiberglass sinks in Phoenix, AZ are durable and beautiful, but they do tend to be a little difficult to keep clean. Fiberglass is sensitive to acids, chemicals and other abrasive cleaning products and techniques. That can present a real problem if you’re dealing with stains or hard water!

Over time, fiberglass can turn dull or dingy and develop stains. That’s because it’s a composite material that’s prone to scratching. The more scratches your sink has, the easier it is for stains to permeate and get trapped in the tiny crevices. You’ll need to take a little extra care when you’re cleaning a fiberglass sink in Phoenix, AZ, but the pro tips below will help prolong its lifespan. If you try them all and still can’t get the results you want, it may be time to refinish your sink—at a fraction of the cost it would be to replace it. Call the pros at A-1 Porcelain & Fiberglass Service Co., L.L.C. for more information on how you can revitalize your fiberglass tub or sink.

Cleaning fiberglass

Exercise caution when scrubbing your sink—too much acid and pressure can damage the material. Here are some approaches you can try:

  • Scrub with baking soda and warm water: Using a soft cloth or sponge, dampen the cloth and sprinkle baking soda over it. Scrub the sink using medium pressure, aiming to remove water deposits, dirt and mineral stains. Use another damp cloth to remove the baking soda.
  • Mild abrasives: If you’re still having trouble with stubborn stains, try a mild abrasive cleanser. We like Bon Ami, Brill-Glow or Soft Scrub. These should allow you to scrub away deeper stains without damaging the fiberglass’ surface. After you’re finished scrubbing, rinse with warm water.
  • Calcium removers: Products like CLR, Lime-A-Way and even simple 5 percent white vinegar are safe enough to use on fiberglass, sparingly. (Don’t use this trick in your weekly bathroom wipe-down!) Use according to the manufacturer’s instructions, and wipe down with warm water.
  • Oxygen bleach as a last resort: If you still can’t get those stains out after trying the above methods, you can use oxygen bleach as a last resort. Oxygen bleach can be purchased, but you can also make your own version. Mix one part hydrogen peroxide, one part baking soda and two parts hot water. Then simply apply to the stains (and only the stains), wait an hour and rinse away.

Other sources recommend solvents such as acetone (found in nail polish remover) for stains. Be cautious when using any abrasive, as they can shorten the lifespan of your fiberglass sink.
