Rust-oleum 300112 Rust Dissolver Gel 32 Oz

Product Description

The RUST-OLEUM 300112 is a 32 oz gel-formula rust dissolver designed to remove rust from iron, steel, and other metal surfaces. The gel consistency keeps the formula in contact with the corroded surface rather than running off, which allows the active chemistry to work without constant reapplication. Once rust is dissolved, the formula leaves behind a corrosion inhibitor that protects bare metal for up to 12 months. This product is used by HVAC technicians, plumbers, pipefitters, and maintenance professionals who need a reliable rust-removal solution on metal components during service or restoration work.

The 300112 is suited for both residential and light commercial maintenance applications. It performs well on metal pipe, brackets, fasteners, housings, and structural steel that have developed surface rust. The gel format is particularly useful on vertical or overhead surfaces where a liquid product would drain away before the formula could activate. Facilities maintenance crews and field service technicians use it as part of pre-treatment work before painting, coating, or reassembly.

Key Features

• Gel formula clings to vertical and irregular metal surfaces to keep chemistry activated
• Removes surface rust from iron, steel, and other metals
• Corrosion inhibitor protects bare metal for up to 12 months after treatment
• Creates a clean surface suitable for painting or coating after rust removal
• 32 oz single-unit container for field or shop use

Compatibility

Designed for use on iron, steel, and other metal surfaces where surface rust removal and post-treatment corrosion protection are required.

Installation Notes

Applied by maintenance professionals, pipefitters, and service technicians working on metal components. Before applying, ensure the work area is adequately ventilated and wear appropriate chemical-resistant gloves and eye protection. Allow sufficient dwell time as directed on the product label before rinsing or wiping the treated surface. Do not apply to painted surfaces unless full stripping is intended, and verify material compatibility before treating non-ferrous metals beyond iron and steel.
