How to Clean and Maintain Your Security Screen Doors & Windows (Care Guide) Your Crimsafe security screens are built to last — with 304 structural-grade stainless steel mesh that has a natural lifespan of approximately 65 years. But like any premium product installed on the exterior of your home, they perform best when they receive regular care and attention. Properly maintaining your security screens keeps them looking great, functioning at peak performance, and ensures your 10-year Crimsafe warranty remains valid. The good news? The process is simple and takes just minutes. Why Regular Cleaning Matters for Security Screens Security screens are installed on the exterior of your home, which means they’re exposed to the elements around the clock. Over time, dirt, dust, pollen, and airborne impurities can accumulate in the mesh weave. If left untreated, this buildup can give your screens a stained or discolored appearance. Two specific environmental factors require extra attention: Salt exposure: If you live near the coast, airborne salt can deposit on your screens and appear as fluffy white marks. The closer you are to the ocean, the more frequently you’ll need to clean. Moisture and pollutants: In humid or urban environments, moisture combined with airborne impurities can cause reddish marks on the mesh surface. This isn’t rust — it’s surface contamination from external particles. Regular cleaning removes these contaminants before they have a chance to affect the protective powder coating on your mesh. This coating is what protects the stainless steel underneath, so keeping it intact is essential to the long-term performance of your screens. Step-by-Step Security Screen Cleaning Guide Follow these steps to keep your Crimsafe screens in like-new condition: Rinse the entire screen — both the frame and the mesh — with clean water to remove loose dirt and debris. A standard garden hose works well for this. Using a soft, non-abrasive brush (such as a soft-bristle car wash brush), gently scrub the mesh and frame to loosen any remaining buildup. Work in gentle, even strokes. Wipe down the mesh and frame with a fresh, soft microfiber cloth dampened with clean water. This removes any residual dirt and polishes the surface. Rinse once more with clean water and allow the screen to air dry. That’s it. The entire process typically takes 5–10 minutes per screen. What NOT to Do To protect your screens and your warranty, avoid the following: Do not use abrasive cleaners, scouring pads, or steel wool — these will damage the powder coating. Do not use strong solvent-based cleaners, bleach, or ammonia-based products. Do not use a pressure washer — the high-pressure spray can damage the mesh and coating. Do not allow saltwater, pool chemicals, or fertilizer to sit on the mesh without rinsing. How Often Should You Clean Your Security Screens? The frequency of cleaning depends on your environment and location. Use the guide below as a starting point: Environment Recommended Frequency Why Coastal (within 5 km of ocean) Every 3 months Salt spray accumulates quickly and can compromise the powder coating Urban / Suburban Every 6 months Pollution, dust, and moisture buildup at a moderate rate Rural / Inland Once a year Lower exposure to salt and pollutants, but pollen and dust still accumulate Pool-adjacent screens Monthly rinse Chlorinated water and chemicals can be corrosive if left on surfaces Your Crimsafe installation technician will assess your specific environment during installation and provide personalized care recommendations based on your location. Learn what makes Crimsafe’s stainless steel mesh so strong What Causes Discoloration on Security Screens and How to Prevent It Crimsafe mesh is made from 304-grade stainless steel, which is naturally resistant to corrosion. However, the key to long-term performance is keeping the factory-applied powder coating intact. This coating serves as the primary barrier between the stainless steel and the environment. If the powder coating is compromised — through abrasive cleaning, physical damage, or prolonged exposure to corrosive elements — the exposed steel can become susceptible to surface staining. This is not structural rust, but it will affect the appearance of your screens. The best prevention is simple: clean regularly, use gentle products, and rinse after any exposure to salt, chemicals, or construction dust. Important: Failure to follow the recommended care guide may void your product warranty. Taking a few minutes to care for your screens protects both their appearance and your investment.
