Caring for Cast Iron Radiators: Paint, Clean & Preserve

Cast iron radiators are functional art. Proper care ensures lifetime performance and beauty.

Installation Foundation

Correct installation = lifetime service. Ensure heating system compatibility. Add corrosion inhibitor to system water—prevents internal rust, eliminates flushing needs, keeps system efficient.

Painting Done Right

• Use radiator-specific paint: adheres to metal/undercoat, dries to hard gloss
• Multiple thin coats + light sanding between = best finish
• Spray paint formulated for radiators works too
• Radiator MUST be cold and off during painting + full cure time
• Best: have manufacturer paint to your color spec

Cleaning Without Damage

• Damp cloth wipe-down periodically
• Vacuum attachments for column/grille dust
• NO cleaning products—damages finish
• Some models allow side-plate removal for internal vacuuming

Display, Don't Hide

Cast iron radiators are meant to be seen. Keep furniture clear. They're conversation pieces that anchor a room's design.
