"F9 BARC: The Ultimate Rust and Stain Remover for Professional Pressure Washing"

The F9 BARC Comprehensive Rust and Stain Remover is an industrial-grade cleaning solution specifically designed for professional use. It effectively removes a wide range of stains, including heavy rust, fertilizer stains, orange battery acid stains, and snow plow blade rust, across multiple surfaces.

Key Features:

  • Multi-Surface Compatibility: Designed for a wide array of surfaces like concrete, bricks, pavers, stone, stucco, and pool decks.
  • Concentrated Formula: Economical usage allows multiple jobs to be completed with a single bottle.
  • Efficient Stain Removal: Targets a variety of tough stains like orange battery acid, heavy rust, and fertilizer marks.
  • Eco-Safety: Biodegradable, non-abrasive, and non-flammable. A safer choice for People and Plants than Hydrochloric Acid.
  • Precise Application: Apply F9 BARC using a conical (round pattern) tip, as a spray rather than a stream. Ensure the product adheres to the surface up to the point of almost running down. No scrubbing or agitation is needed; just allow the product to soak in.
  • Technical Assistance: Toll-free customer support and online resources for comprehensive guidance. 855-803-1133 or online at www.Front9Restoration


  • Dilution Range: Can be diluted with up to 3 gallons of water for surfaces other than concrete.
  • Preferred Method: Pre-cleaning with professional power washing is recommended for best results.

For specialized rust challenges originating from metal furniture, fixtures, or pyrite, or in cases of particularly thick or heavy rust, a pre-treatment with F9 Efflo diluted at a ratio from 4:1 to 10:1 with water is recommended. Apply and scrub the affected areas before proceeding with F9 BARC for effective rust removal.
