Application :

For parts cleaning, rust removal and surface preparation prior to painting in automotive and industrial applications.

Dose :

Equipment : 

Customer Owned Machines Immersion (other common terms – Vats, Dip Tanks, Hot Tanks).

Note: Tanks (Vats) should be made of stainless steel (304, 316, or 347), ceramics or other acid proof materials. Heating elements should be made of stainless steel, impervious carbon or graphite. Do not use Monel equipment, lead or rubber lining in tanks.

Soils : 

Light to moderate grease and oil. Light to heavy rust, heat scale, flux, and other oxides.

Operating Instructions:

Immersion: Use 5% to 25% volume with water at room temperature to 160ºF. Follow the cleaning step with fresh water rinsing and drying. The higher the concentration and heat, the faster the rust removal. Immersion time depends on the degree of soil and amount of rust to be removed. Hand Wipe: Use 10% to 50%/volume added to water at room temperature to 120ºF. Apply with clean rags, wipes or brushes. Allow the Rust Remover to soak on part surfaces for several minutes before wiping or brushing for improved results. Follow with fresh water rinsing then dry the parts.
