53G248 - Walter BIO-RUST Neutral pH Rust Remover Liquid 208L Drum

Industrial-Grade Neutral pH Rust Removal Solution

The Walter BIO-RUST (SKU: 53G248) in the 208-liter drum format is a premier solution for industrial-scale rust removal operations. Engineered for safety and efficiency, this liquid formulation utilizes a neutral pH chemistry that selectively targets iron oxide (rust) without compromising the integrity of the underlying ferrous substrate. Unlike traditional acid-based pickling agents or caustic strippers, BIO-RUST eliminates the risks associated with handling hazardous chemicals, making it a compliant choice under OSHA and WHMIS regulations. It is non-flammable, solvent-free, phosphate-free, and contains no Volatile Organic Compounds (VOCs), ensuring a safer workplace environment and simplified disposal protocols.

This product is specifically designed for immersion applications. The 208L drum is ideal for filling large soak tanks used in maintenance, repair, and overhaul (MRO) facilities or manufacturing plants. The solution boasts a high workload capacity, capable of sequestering approximately 1.0kg (2.2lbs) of iron oxide for every 20 liters of fluid, providing a long active bath life before replacement is necessary. Furthermore, BIO-RUST is NSF Category A2 registered, validating its suitability for use in and around food processing areas (where not in direct contact with food), provided parts are rinsed effectively.

Technical application involves immersing degreased ferrous parts into the solution at room temperature. The non-destructive nature of the fluid means it can be used on sensitive components where dimensional tolerances must be maintained. It effectively prepares surfaces for subsequent coating or painting by providing a clean, contaminant-free substrate. Post-treatment simply requires a water rinse to remove loosened contaminants, leaving the metal surface bright and ready for use or further processing.
