How to Deal with White Spots on Window Trim?

You can try chrome polish, which works very well. Alternatively, toothpaste, toilet cleaner, WD-40 multi-purpose rust preventive, etc., can also be used for removal. You can sand it with rubbing compound and then wipe it clean with water.
White spots on window trim strips are quite common, usually caused by oxidation or water stains. When dealing with them myself, I first gently scrub with neutral car wash soap and a soft-bristle brush. For stubborn spots, I apply specialized metal polish and buff it off with a microfiber cloth using circular motions. After cleaning, don't forget to apply a layer of automotive protective wax to prevent water stains from penetrating. Always make sure to thoroughly dry the trim areas after washing, especially in northern winters when road salt is highly corrosive - immediate rinsing is crucial. Weekly simple cleaning helps prevent white spot buildup, maintaining both appearance and trim longevity, which is much more convenient than frequent replacements.
