Karcher 9.803-746.0 : Fleet Aluminum Brightener 5-Gallon Acid-Based Pressure Washer Cleaner for Aluminum Tanks, Trailers & Wheels

Key Product Features:

• Extra-strength acid-based aluminum cleaner and brightener formulated for non-polished aluminum tanks, trailers, wheels, and fleet aluminum surfaces.
• Restores brightness to approved aluminum surfaces by helping remove dull oxidation, road film, smoke staining, and embedded grime.
• Effective on grease, oils, baked-on carbon, and diesel smoke residue, making it ideal for fleet vehicles, tankers, trailers, and work trucks. 
• 5-gallon commercial container provides a practical supply size for truck wash bays, fleet maintenance departments, trailer shops, industrial cleaners, and pressure washing contractors.
• Designed for aluminum surface preparation before painting, helping clean and brighten approved aluminum prior to refinishing work. 
• Economical dilution range of 1:5 to 1:20, allowing 5 gallons to produce up to approximately 105 gallons of ready-to-use solution depending on soil level. 
• Heavy soil dilution of 1:5 is recommended for tougher buildup, while light soil dilution of 1:20 supports routine brightening and maintenance cleaning. 
• Low-foaming formula helps improve rinsing efficiency and supports professional pressure washer cleaning workflows. 
• Safer than hydrofluoric acid products, with Kärcher literature noting it uses ammonium bifluoride rather than hydrofluoric acid. 
• Compatible with downstream injector application only; do not run this product through a high-pressure pump to avoid equipment damage. 
• Best used with pressure washer or brush cleaning, followed by a thorough clean-water rinse for professional results. 
• Ideal for non-polished aluminum tanks, fuel tanks, trailers, aluminum wheels, fleet aluminum panels, truck bodies, and aluminum parts being prepared for paint.
• Important surface warning: Do not use on glass, polished aluminum, or anodized aluminum; always follow the label directions and test first in an inconspicuous area. 
• Packaged size listed by Kärcher: 5 gallons, with packaged dimensions approximately 12.4 x 15.7 x 12.2 inches. 
• Ideal users include trucking companies, tanker fleets, trailer maintenance shops, truck wash operators, transportation companies, municipalities, farms, industrial plants, and commercial pressure washing contractors.
