Safety first: Wear suitable eye and hand protection, follow product labels, work with ventilation, and avoid damaging load-bearing or safety-critical parts. Consult a qualified professional when structural integrity is in doubt.
Rust removers
These products aim to remove corrosion from a surface. Methods and chemical formulations differ, so check material compatibility.
Rust converters
These treatments chemically react with remaining rust and are generally used as part of a coating system. They do not restore lost metal.
Which should you choose?
Use the product specified by the surface-preparation and coating system. Remove loose rust and contamination first, and follow cure and topcoat instructions.
Safety and limitations
Avoid mixing chemicals. Do not treat heavily corroded structural components as sound without inspection.
