Since there is a degree of variability in the appearance of the finish from batch to batch, we recommend establishing an installation technique, similar to the way shingle roofs are installed, whereby the installer works from a few different crates of panels on the job site, so as to distribute panels with certain finish attributes over a wide area, co-mingled with panels made from other sheets. InvariMatte® Walnut is shipped with a high-grade UV resistant protective plastic covering designed to withstand the elements for several weeks. However, it is advisable to remove this material promptly after installation to prevent adhesive residue from remaining on the colorized stainless steel finish. After installation is completed, any rust stains from tools or construction debris must be removed

Maintenance
Designed to be essentially maintenance free, InvariLux® will last for decades without requiring attention. It may, however, be appropriate to clean the surface to maintain its original appearance. Specific stainless steel agents are available on the market. Any detergent/ammonia solution can be effective for general cleaning. A sodium carbonate paste can be applied with a warm water rinse to address stains. Severe stains can be removed with tri-sodium phosphate and caustic soda solutions. More tenacious contaminants, like adhesive residue will respond to pure acetone. Chloride-containing products must be avoided. Areas where incidental debris can collect, such as gutters, must be cleaned on a regular basis
