Description:
Rust Killer is a high quality heavy duty acid cleaner specially designed for rust removal from concrete, masonry, wood and other hard surfaces. Rust Killer will remove rust stains created by sprinkler systems, railings or other exterior steel structures. It will also remove red clay stains, yellow boat bottom stains, organic stains from berries and trees, and battery rust.
Directions:
For best results, use Rust Killer at full strength. Soak the stained area with products and allow it sit for 2-3 minutes. If the rust stain is on wood, allow this product to fully penetrate the wood. Rinse the surface thoroughly with a pressure washer. For the deepest and most stubborn stains, repeat this process until the stain is removed.
