Crimsafe mesh acts similarly to an air conditioner filter or a pool filter, in that it traps dirt and impurities and requires cleaning on a regular basis.
Regular maintenance involves a wash down of frames and mesh with Crimsafe Wash and Wax in warm water using a soft bristle brush, followed by a clean water rinse. You should clean your Crimsafe screens in accordance with this guide.
With the coating on Crimsafe intact, it will not rust. If it does chip off, you can rest easy knowing this fact - stainless steel has a high corrosion resistance; uncoated steel can last up to 60 years before signs of rusting
