Metalic Brightner HD is Cargo hold and Tank cleaning chemicals. Which is also useful products for Deck and maintenance cleaning and rust removing.
Before application of Metalic Brightner HD, we have to understand its cleaning principal...
In general terms and thumb rule for Metalic Brightner HD is MORE RUST required more Metalic Brightner HD. Chemically Rust { iron oxide (FeO) } is soluble in pH values below 4.0, . Thus, the oxide (oxygen) dissolves as it is formed instead of depositing on the metal's surface. So it is clear more rust required more Metalic Brightner HD to get dissolve. In practical if the area is fully rusted corroded then direct Metalic Brightner HD can be used to dissolve rust particles, while in light contaminated part Metalic Brightner HD can be diluted in between 20 to 70% .
2nd factor is the time which is directly affecting the cleaning result. If base metal is aluminium then use Metalic Brightner HD concentration 10 to 30% for not more then 5 Minutes. For removal of rust stains on painted or iron surfaces, use 10–30% of Metalic Brightner HD soultion for 15–20 minutes. And for heavily rusted and corroded or soiled surfaces and tarnish on copper and brass, use a solution of 20–50%, for 15–40 minutes.
The 3rd important point always be noted, After cleaning of rust from Metalic Brightner HD all area should be fully rinsed and clean properly with fresh water. And for best long time result to keep rust free surface, Surface can be chemically
neutralized with
RXSOL-41-8896-025 ( dilution ration 1 Ltr RXSOL-41-8896-025 with 10 Ltr water ). The scientific reason behind that is As With the Rust oxide gone with Metalic Brightner HD, the metal surface is in direct contact with the acidic solution, and the corrosion reaction proceeds at a greater rate than it does at higher pH values. For increasing pH values greater than pH 10, the rusting rate seems to fall as pH is increased with help of
RXSOL-41-8896-025.
