• Trusted by professionals for over two decades, F-13 is a quality solution you can count on.
• Oxidation Layer Removal: Specially designed to tackle the root cause of stubborn black streaks/tiger stripes on your gutters, F-13 targets and eliminates the oxidation layer of paint.
• Versatile Dilution: F-13 offers cost-effectiveness like no other. Unlike butyl-based products that lose strength when diluted with water, F-13 remains highly effective even at dilution ratios as high as 50-1. For tougher stains, you can use F-13 at lower dilution ratios, ensuring the right strength for every cleaning task.
• Economical Choice: With F-13, you get excellent value for your money. A 20-1 dilution typically removes oxidation and brightens gutters with minimal effort, saving you time and money while delivering superior results.
• Efficient and Effective: F-13 is your reliable ally in the fight against gutter stains. With a bit of agitation, it quickly works its magic, eradicating oxidation and restoring the pristine appearance of your gutters.
