Directions for use

Dosing method
Unitor™ Metal Brite H.D. should always be used in a plastic bucket. Acid should always be added to water, never the reverse. Remove dirt, rust flakes, oil and grease prior to using Unitor™ Metal Brite H.D.

Apply Unitor™ Metal Brite H.D. to surfaces to be cleaned or pickled as follows:

For severely corroded surfaces and pickling of welding repairs, use 50% solution to neat.

For less severely corroded or soiled surfaces and tarnish on copper and brass, use a solution of 20--50%, and rinse off surface after 15--40 minutes with water.

On aluminium, use a solution of 10--30%, but rinse off surface maximum 5 minutes after application.

For removal of rust stains on painted surfaces, a solution of 10--30% should be sufficient. Rinse off with water 15--20 minutes after application.

For removal of rust stains on ceramic tiles, enamels, porcelain, glass etc., use a solution of 20--50%, depending on stains and soiling. Rinse off with water after 20--40 minutes.

For removal of light cement stains and lime, apply a 50% solution, and high pressure wash after 30--40 minutes, and for solidified cement use Unitor™ Descaling Liquid.

For removal of light rust and scale in pipelines and tanks, recirculate a solution of 5--10% Unitor™ Metal Brite H.D. For discoloration of stainless steel and epoxy coated tanks use the same method.

For removal of white residues from epoxy-coatings that sometimes remains after carriage of Stearin, Olein, Palm fatty acid etc., recirculate a solution of 5--10% Unitor™ Metal Brite H.D. When injected, use a 5% solution. Recirculate or inject until residue is removed.
