About the F9 BARC Concrete Rust Remover

F9 BARC is known to be the world’s best concrete stain remover, offering a specially formulated solution designed to eliminate both orange battery acid and rust stains effectively. This versatile product is capable of tackling a broad spectrum of rust-related issues on various surfaces such as concrete, brick, pavers, stone, stucco, pool decks, asphalt, rubber, epoxies, painted surfaces, concrete coatings, shingles, and more! 
What sets F9 BARC apart is its efficiency in stain removal without the need for labor-intensive tasks like scrubbing, brushing, mixing, or dealing with messy pastes. The formula chemically binds to the concrete, exhibiting a remarkable ability to reverse 80-100% of orange battery or rust staining. As a result, it not only removes unsightly stains but also restores concrete surfaces to their natural gray color.
Additionally, F9 BARC prides itself on being a biodegradable, non-abrasive, and non-flammable solution, prioritizing safety for both people and plants. This concrete stain remover is a much safer alternative to hydrochloric acid, a common yet hazardous substance used for similar purposes.
For optimal results, the recommended pre-application cleaning method is professional power washing. The concentrated formula ensures that a little goes a long way, making it a cost-effective solution. Moreover, for surfaces other than concrete, F9 BARC can be diluted with up to 3 gallons of water. However, a compatibility and strength test is advisable before widespread application.
Please note that F9 BARC boasts a shelf life of up to five years when new and unopened. Once opened, the shelf life is reduced to approximately two and a half years.

How to Use F9 BARC Concrete Rust Remover:

• Pre-cleaning: Power wash the concrete using a commercial-grade pressure washer and surface cleaner.
• After initial pre-cleaning, let the concrete dry completely.
• Apply F9 BARC through a pump-up sprayer liberally and evenly to the entire pad of concrete. Do not "spot spray" the first application.
• Let the concrete dry. Stains will disappear as the concrete dries.
• If spots remain, repeat steps 3 and 4.
• A natural by-product of the reaction of this product and the concrete are light and dark mineral salts. Wet the concrete to reactivate the F9 cleaner. Agritate with broom and rinse LIGHTLY with pressure washer (NOT surface cleaner) to remove the remaining salts.
