All meshes act as a filter, trapping airborne dirt and impurities. A regular wash down with warm soapy water using a sponge or a bristled brush (approximately every 4-6 weeks) followed by a clean water rinse, will keep your Bradnams Crimsafe screens in good condition.
For high salt areas particular care should by taken, as salt will stick to most surfaces, attracting moisture and other airborne impurities. If not kept in check this can cause staining of the mesh, ranging from white salt marks, to red iron oxide marks (common airborne impurities) and deterioration of the frames.
Bradnams Crimsafe will not rust. However, staining caused by a combination of salt, moisture and impurities may result in ‘reddish’ marks if not kept clean. Ultimately, if no maintenance is done, deterioration, particularly in high salt and moisture environments, may result in a breakdown of the product to a corrosive level.
In harsh salt/moisture environments, the Bradnams Crimsafe wire can be protected easily after cleaning with a periodic application of silicone (CRC 808 is recommended) by simply spraying onto a cloth and wiping the surface of the wire.
If you find that marks cannot be removed with the standard cleaning methods, a solution of Phosphoric Acid diluted and used strictly as directed, will remove any stubborn marks.
An example, available from hardware stores, is ‘Plus’ rust converter.
Although the screen itself does not rust, this form of phosphoric acid will remove any metal based contaminants such as iron oxide, as well as salt stains.
NB: Care must be taken not to allow phosphoric acid to touch anodising framing as it may stain anodised surfaces. Again, be sure to follow safety instructions. After a rinse, a quick silicon spray will bring them back to new condition.
