RXSOL-40-1048-025 should not be used on Aluminium, Zinc, Tin, or any Galvanized Surfaces for which a special grade cleaner should be used. Chemical Cleaning Module Rx cleansers has developed a 280 litres capacity cleaning module, primarily designed for use with chemical acid solvents for descaling boilers, calorifiers, heat exchangers & other types of equipment where rust & scale form RXSOL-11-1008--DC Boilers, See Rx cleansers Practical Application Manual.

Formation of Calcium Sulfate is main cause for SCALE formation :::

The principal problem potential posed by sulfate ions in water is the possibility of calcium sulfate scale formation.  Precipitation of calcium sulfate can occur when high concentrations of both calcium and sulfate exist simultaneously.  There are three primary areas of water treatment in which calcium sulfate precipitation may occur boilers, cooling systems, and ion exchangers operating in the hydrogen or acid mode.

In boilers, calcium sulfate scale formation has been reduced to a minimum by modern treatment practices.  The low hardness levels largely preclude calcium sulfate boiler scale.    By contrast, cooling systems are subject to calcium sulfate scale deposition because the makeup is usually not treated for hardness removal.  Cooling water is usually treated with sulfuric acid for pH control, and the makeup is cycled, i.e. concentrated.  Calcium sulfate scale deposition can  result unless the cycles of concentration are properly controlled in conjunction with the proper use of scale control chemicals.  Cation ion exchangers regenerated with sulfuric acid also can pose a major calcium sulfate problem. Calcium sulfate precipitation can be avoided by controlling the acid concentration and the flow rate through the exchanger.

What is METAL BRIGHT MB ?

Phosphoric Acid-Based Ship Cargo Hold Cleaner with Wetting Agents Specified Marine Chemicals : 

RXSOL METAL BRIGHT MB is a powerful acid-based cleaner formulated with phosphoric acid and wetting agents for effective removal of stubborn residues in cargo holds and tanks. It is specially designed to eliminate white lime residues, cement, cement clinker, gypsum, and ore deposits. It is also highly effective against fatty acid residues and caustic soda buildups.

In addition to its cleaning power, RXSOL METAL BRIGHT MB brightens and restores the appearance of metal surfaces such as aluminum, copper, and stainless steel, making it ideal for ship maintenance and cargo tank cleaning.

METAL BRIGHT MB is a high-performance metal surface brightener and descaler, widely used in the marine shipping industry for cleaning and restoring metallic surfaces, especially in engine rooms, cargo areas, and pipelines. It is typically based on inhibited phosphoric acid blended with wetting agents and corrosion inhibitors, making it both effective and safe for use on various metals.

Key Features of RXSOL METAL BRIGHT MB:

• Removes lime, cement, clinker, gypsum, and ore residues

• Effective against fatty acids and caustic soda contamination

• Brightens and cleans aluminum, copper, and stainless steel surfaces

• Contains wetting agents for enhanced cleaning efficiency

• Ideal for cargo hold and tank cleaning operations

• Safe and effective when used as directed

What is Hold Block and why hold block application is better than LIME WASH?

When aggressive or corrosive dry bulk cargoes—such as fertilizers, salt, coal, or sulphur—come into direct contact with the metal surfaces of ship holds, they can cause rapid corrosion and surface degradation due to chemical reactions. This not only weakens the structural integrity of the vessel but also leads to costly repairs and safety risks.

To prevent such reactions and ensure long-lasting surface protection, a polymer-based protective coating is the ideal solution.

Why Use Polymer based HOLD BLOCK Coating in Cargo Holds?

• Chemical Resistance
  Acts as a barrier against corrosive cargoes, preventing direct metal contact and chemical reaction.

• Easy Application
  Applied by brush, roller, or spray before cargo loading. Forms a durable, even protective film.

• Temporary or Voyage-Specific Use
  Perfect for short-term voyages carrying highly reactive cargoes, allowing for easy cleaning and reapplication after discharge.

• Prevents Pitting & Rust Formation
  Shields steel from moisture, acidic residues, and abrasion, reducing long-term maintenance costs.

Field and Typical Applications of HOLD BLOCK

• Sulphur

• Salt

• Phosphates

• Urea

• Coal & Petcoke

• Cement

• Bauxite

Why Hold Block is better choice than LIME COATING

• Polymer-based water-resistant coating

• Safe on all standard marine metal surfaces

• Compatible with hold cleaning chemicals

• Non-reactive, non-toxic, and easy to remove

• Protects for the entire duration of cargo voyage

Recommended Use of Cargo Hold Block 

Apply 1–2 coats uniformly across cargo hold surfaces prior to loading reactive cargo. For enhanced protection, focus on:

• Tank tops

• Bulkheads

• Frames and internal structures

• Hatch coamings
