Directions for use

Unitor™ Metal Brite™ should always be used in a plastic bucket. The acid should always be added to water, never the reverse.

For removal of rust stains and oxide stains on aluminium, brass, copper and stainless steel, apply Unitor™ Metal Brite (after removal of oil and grease) neat with a brush, rag, etc. Wash off after 15 minutes. Repeat if necessary. Do not let Unitor™ Metal Brite™ dry on surfaces as it may leave a hard white deposit.

For steel surfaces remove oil, grease and old paint. Wet down the entire surface with neat Unitor™ Metal Brite™ and allow to dry. Second wash may be necessary. Surface should have a grey/white appearance when the Unitor™ Metal Brite™ is dry. Steel surfaces will have a resistance to rust and will render a good base for paint.

For removal of rust stains on painted surfaces and wood, Unitor™ Metal Brite™ should be applied at full strength for heavy stains, or diluted to 30--50% for light stains. Allow to soak for 20 to 30 minutes and wash off with water. A second application may be necessary to remove the stubborn stains.
