Maintaining polycarbonate panels is a simple yet essential process to preserve the durability and aesthetic appearance of this modern material. Whether we’re talking about solid polycarbonate panels, multiwall sheets, or corrugated polycarbonate, all require regular care.
Exposure to dust, pollen, acid rain, or ultraviolet rays can affect their transparency and strength over time. Proper cleaning and UV protection are essential steps to ensure that your roof, terrace, or decorative wall maintains its qualities for years.
A clean polycarbonate panel not only looks better but also performs better. Light passes more easily through a well-maintained surface, and the structure keeps its mechanical strength.
Unlike other materials such as glass or plexiglass, polycarbonate has the advantage of being impact-resistant and not breaking easily. However, to avoid scratches and surface damage, it’s important to use the right cleaning products and techniques.
In our experience, we often see projects where panels were installed perfectly but deteriorated due to a lack of regular maintenance. A simple cleaning and UV protection routine can make the difference between polycarbonate that stays crystal clear and one that becomes dull and brittle.
How to Properly Clean Polycarbonate Panels
Cleaning polycarbonate doesn’t have to be complicated, but you should follow a few key rules. Unlike glass, this material can be sensitive to harsh chemicals.
Useful Cleaning Tips:
-
Use lukewarm water and neutral liquid soap.
-
Avoid cleaners that contain ammonia, alcohol, or strong solvents.
-
Always rinse the surface thoroughly to remove all detergent residue.
-
Dry with a soft microfiber cloth to prevent water spots.
For large panels, such as those used in roofs or pergolas, we recommend using a soft brush with a telescopic handle. It helps you reach difficult areas without applying excessive pressure.
If you’re using multiwall polycarbonate sheets, remember that these structures have internal channels that can trap dust or debris. It’s important to clean the edges and use end caps or closing profiles — available in our range of polycarbonate accessories — to prevent dirt buildup.
Preventing Scratches and Mechanical Damage
Although polycarbonate is a strong material, it can still scratch if cleaned with rough sponges or metal brushes. Once they appear, scratches are hard to remove and can reduce transparency.
For optimal protection:
-
Avoid washing panels in direct sunlight, as water evaporates quickly and leaves marks.
-
Use only soft cloths or special sponges.
-
Do not use high-pressure water jets, which can damage joints and seals.
For modern constructions, regular maintenance not only ensures material durability but also helps maintain the elegant design. Mechanical protection is especially important in areas exposed to wind, falling leaves, or branches.
UV Protection for Polycarbonate Panels
An important part of polycarbonate maintenance is protection against ultraviolet rays. Modern panels come with a protective coating, but over time it needs care and renewal.
Continuous sun exposure can cause:
-
Surface yellowing,
-
Loss of transparency,
-
Visible microcracks.
To prevent these issues, we recommend applying specialized UV protection solutions periodically. These products create a thin film that restores the original protective layer and extends the panel’s lifespan.
If you’re using corrugated or trapezoidal polycarbonate — common in roofing or industrial applications — UV protection is even more critical. In our industrial-grade product line, this aspect is key to ensuring long-term performance.
Differences Between Polycarbonate and Plexiglass Maintenance
Many clients ask about the difference between polycarbonate and plexiglass in terms of maintenance. Both materials are transparent and used in construction or decorative projects, but their behavior differs.
-
Solid polycarbonate is more impact-resistant but requires consistent UV protection.
-
Plexiglass (acrylic sheets) has a harder surface, making it more scratch-resistant but more fragile upon impact.
-
Maintaining plexiglass requires gentler cleaning products, as it can dull more easily.
On our website, you can find a wide range of acrylic sheets ideal for projects where aesthetics are a priority and careful maintenance is key. The choice between the two materials depends on the application, but both perform excellently with proper care.
Long-Term Maintenance and Practical Tips
To keep your polycarbonate panels in great condition for years, it’s best to follow a simple maintenance routine.
Our recommendations:
-
Clean the panels at least twice a year — in spring and autumn.
-
Periodically check joints and seals.
-
Apply UV protection every two to three years, depending on exposure.
-
Remove leaves and debris after storms.
Another tip: use proper accessories for fastening and sealing. These not only make installation easier but also prevent dirt buildup and water infiltration. Plus, correct installation extends the lifespan of your panels and reduces maintenance costs.
Maintaining polycarbonate panels makes the difference between a material that stays beautiful and one that degrades quickly. Regular cleaning, UV protection, and proper accessories are simple but crucial steps.
