How to Deal with Corrosion on Chrome Trims?

Toothpaste contains antioxidants and abrasive particles for stain removal. Dampen a towel with toothpaste and polish, though it may struggle with stubborn rust spots. Toilet cleaner also contains dilute hydrochloric acid, which can chemically react with oxides. After dissolving the oxides, wipe them clean with a damp towel. WD-40 has strong surface affinity and permeability for metals, forming an ultra-thin, dense protective film to block moisture and air. It can remove stubborn stains like oil and adhesive residues. The method is to spray it on the stained chrome trim first, then wipe clean with a damp towel.
My old car's chrome trim had the same issue before, and I managed to fix it myself. First, thoroughly clean the chrome trim surface with car wash soap, rinsing off all the dirt, paying special attention to the whitish areas. Then, take the finest sandpaper, wet it slightly, and gently sand the corroded spots—controlling the pressure is crucial. After sanding, apply metal-specific polishing compound and rub in circular motions with a soft cloth for about ten minutes; you'll see black grime being removed. Finally, rinse with clean water and spray on rust-preventive protectant. Never neglect regular maintenance—always dry water spots after washing, and promptly clean off bird droppings or tree sap if parked under trees, otherwise you'll have to redo the work in three months. For those less handy, I'd recommend visiting a detailing shop since their professional equipment delivers more thorough results.
