How to Clean an FRP Wall Panel

Nick Davis

Fiberglass Reinforced Plastic wall panels are durable, and repel stains, bacteria, mold and mildew growth. The panels are quick to install on ceilings and walls. But, like sheet rock and other wallboard, FRP wall panels are not immune to dust and dirt buildup.

You don’t need a specialized cleaner to remove debris from the panels. Cleaners you already have in your home or business, along with several other basic household supplies, are all you need to keep your FRP wall panels dirt-free.


Avoid using an abrasive sponge, scrub brush or cleaner on your FRP wall panels. These items will scratch the panels and damage them. Apply 2 tbsp. of mineral spirits to a small cloth or rag and scrub any areas of your FRP wall panels containing stickers and/or adhesive to break and remove the debris. Clean your FRP on a weekly or biweekly basis to keep debris from building up on the surfaces.

  1. Mix in a bucket 1/2 cup of liquid soap and 1/2 gallon of warm water. Wear latex gloves to keep your hands clean. Stir the mixture with a sponge or soft scrub brush. Fill another bucket with 1/2 gallon of warm water and set the bucket off to the side.

  2. Move any furniture, rugs or accessories sitting next to or on the FRP wall panels to another room or area.

  3. Wring out excess mixture and scrub one FRP wall panel section with the mixture-soaked sponge or scrub brush. Re-dip the sponge or scrub brush in the mixture, wring out the excess and continue scrubbing the wall panel section until it is clean. For stubborn stains, spray the stain with a general-purpose household cleaner and let it stand for five to 10 minutes. Scrub the stain vigorously with the damp sponge or scrub brush.

  4. Dip a large, soft cloth or rag in the bucket of warm water you set off to the side in Step 1. Wring out the excess and wipe the FRP wall panel you just cleaned to remove any mixture residue and remaining debris.

  5. Re-dip the sponge or scrub brush in the bucket containing soap mixture and repeat Steps 3 and 4 for the next FRP wall panel section that needs cleaning.

  6. Dry the wall panels with a clean, large cloth or rag.
