 ANTI RUSTING LIQUID SOLUTION allows flexibility to customize the length of protection required and the applied cost per square foot (or m2). ANTI RUSTING LIQUID SOLUTION  forms a solution in water and is applied to metal surfaces by spraying or dipping. It is easly soluble in water and provide resistance against bactria and proterct fungus also.

When copper surface is exposed to atmosphere, Initially, the copper darkens, and takes on a black appearance as the copper oxidises to cupric oxide CuO. Then the carbon dioxide in the air, dissolved in water to form carbonic acid, H2CO3, will attack the basic copper oxide to form hydrated copper carbonate resulting pastel green on copper items.

Using Application :
Oxalic Acid is used extensively for boat cleaning, it can be used on timber, GRP and steel craft for the removal of rust and waterline stains and also to clean timber decks. For vertical applications oxalic can be mixed with wallpaper paste to make a thick solution, this mix will cling to any vertical surface and can be washed off with water.


REMOVAL OF IRON STAINS
Iron stains can be removed by scrubbing the stained area with an aqueous solution of oxalic acid in water. Dissolve 1 Ltr oxalic acid Liquid to 2Lt of warm water. Scrub stained area using a stiff-bristle brush. Thoroughly rinse with water after treatment. When completely dry, lightly sand the surface. Surface must be clean and
completely dry (not just surface dry) before refinishing. Incomplete drying and retained subsurface moisture can cause finish adhesion failure.

REMOVAL OF BLACK WATER AND TANNIN STAIN
A common form of staining on wood surfaces results from contamination with iron. A portion of the extractives in wood includes a group of chemicals collectively called tannins. The amount of tannins depends on species; oak, redwood, and cedar are rich in tannins. Tannins react with iron to form a blue-black stain on wood. Common causes of iron stain include use of un-galvanized or poorly galvanized fasteners; OXALIC ACID brushed into the stains makes removal easy. Finishing wood with a WATER REPELLANT WITHA PRESERVATIVE AND/OR  WOOD POLISH OR  OIL greatly minimizes further iron stain and enhances the finish of the wood.. Wood must be clean; free of paint, waxes, oils and dirt. Use wood cleaners to remove any grease oils or grime. Use paint strippers to remove any finish, paint or coating.
