Tenax TeRust 8 oz. Rust Stain Remover Poultice Powder for Granite, Marble, & Natural Stone

TeRust Rust Remover Powder is designed to eliminate rust stains from granite, marble, travertine, limestone, terrazzo, concrete, brick, and sanded grout. It contains a special blend of chelates that effectively remove rust stains from stone. Using the stain process reversal technique, TeRust Rust Remover powder pulls the rust stains out of the stone. Instructions for Use: Scoop out the required amount of powder. Add water and mix to form a toothpaste-like consistency. Apply to the stained area, cover with plastic wrap, and poke several small holes in the wrap using a toothpick. After 24-48 hours, once the powder has dried, remove the poultice, and the rust stain will be gone! Note: Calcium-based stones may etch and require re-polishing after use.
