Another method is to use a heat gun to soften the paint and then scrape it off with a putty knife. Additionally, you can try soaking the metal in a solution of hot water and baking soda to help loosen the paint before scrubbing it off. Always wear protective gloves and work in a well-ventilated area when using chemical paint strippers. **
