Here is a comprehensive guide to keeping your PVC projects looking pristine for years to come.
One of the primary reasons architects and designers choose PVC Foam Board is its reputation as a "set it and forget it" material. It doesn't rot like wood or rust like metal.
However, "low maintenance" does not mean "no maintenance." Whether you have installed waterproof bathroom cabinets or are storing advertising boards for the next season, a little care goes a long way. This guide outlines the simple yet professional techniques to maintain the high-quality finish of the sheets found in our Jinbao PVC Foam Board Collection.
Before diving into cleaning, it helps to understand what you are working with. PVC foam board is a closed-cell plastic.
Chemical Resistance: It resists salts, acids, and alkalis.
Waterproof: It absorbs no moisture, meaning you can wash it freely.
The Vulnerability: Its main enemy is abrasion (scratches) and strong solvents (which can melt the surface).
Keeping your PVC surfaces clean is incredibly simple if you follow the right steps.
Never use steel wool, scouring pads, or stiff brushes. These will leave micro-scratches that dull the glossy or matte finish over time.
Best Tool: A microfiber cloth or a soft cotton sponge.
Best Cleaner: Warm water mixed with a mild dish soap or a dedicated plastic cleaner.
Did someone draw on your board or spill grease?
Ink/Grease: Isopropyl Alcohol (IPA) is generally safe for quick wipes. Apply it to a cloth, wipe the stain gently, and immediately rinse with water.
Adhesive Residue: Use a citrus-based cleaner (like Goo Gone) to remove sticker residue.
Never use the following on PVC foam board:
Acetone or Lacquer Thinner: These solvents will chemically melt the PVC, leaving permanent damage.
Abrasive Powders: Scouring powders will ruin the smooth surface texture.
If you are a commercial user or a sign shop holding stock from our Product List, proper storage is vital to prevent warping.
PVC is a thermoplastic; it has a "memory." If you lean a large sheet against a wall for months, it will eventually bow.
The Fix: Always stack boards flat on a pallet or a level floor.
Support: Ensure the pallet supports the entire length of the sheet. Overhanging edges will droop over time.
While installed PVC handles weather well, loose sheets in storage are more sensitive.
Avoid Heat: Do not store sheets in direct sunlight or near heaters before installation. Uneven heating can cause the protective film to bake onto the surface, making it hard to peel off later.
Periodically check your installation.
Scratches: Minor surface scratches can often be buffed out using a specialized plastic polish or a heat gun (carefully applied) to re-flow the surface.
Sealants: If used in a bathroom, check the silicone caulk around the edges. While the PVC won't rot, the caulk might need refreshing.
Category | ✅ DO | ❌ DON'T |
Cleaning | Use microfiber cloths and mild soap. | Use steel wool or scouring pads. |
Solvents | Use Alcohol (sparingly) or Citrus cleaners. | Use Acetone, Benzene, or Thinner. |
Storage | Stack flat on a level surface. | Lean vertically against a wall for long periods. |
Environment | Keep away from extreme heat sources. | Leave protective film on in direct sun. |
The beauty of PVC foam board lies in its resilience. With just a basic cleaning routine and proper storage, it will maintain its structural integrity and aesthetic appeal for decades. It is an investment that respects your time.

A: Yes! If your board looks tired after years of use, clean it thoroughly with alcohol, lightly sand it with fine-grit paper, and apply a fresh coat of high-quality acrylic latex paint.
A: For very light hairline scratches, a plastic polish (like those used for car headlights) can work. For deeper scratches, you can fill them with a PVC filler, sand it smooth, and paint over the area.
A: Standard PVC can yellow slightly over many years of UV exposure. However, our high-quality boards contain UV stabilizers to minimize this. Regular cleaning removes dirt that can accelerate surface degradation.
A: Yes, but use a low-pressure setting (wide fan spray). High-pressure concentrated jets can damage the surface foam structure if held too close.
