Paint Scraper Technique
A paint scraper is an effective tool for removing paint. Here are a few tips on how to:

Get a scraper with a blade appropriate for your metal surface.
Hold the scraper at a 45-degree angle to the surface.
Apply firm, even pressure to remove the paint.
Work in small sections, being careful not to gouge the metal.
This method is best for flat surfaces and areas where the paint is already flaking or loose.

Chemical Methods For Paint Removal
Chemical paint removers can be highly effective, especially for intricate surfaces or stubborn paint layers. However, they require careful handling and proper safety measures.

Chemical paint stripper should be applied to the metal using a disposable paintbrush, and let it set according to the instructions. You should see the paint bubble up from the metal surface as it sets. Take a paint scraper and scrape off the bubbled paint from all the metal’s flat surfaces.
