How do I remove rust from a metal door?
assistant
To remove rust from a metal door, you can use a mixture of baking soda and water. Mix the two ingredients together in equal parts, then apply it to the rusted area with a soft cloth or sponge. Leave it on for 15 minutes, then scrub off any excess with a damp cloth. Rinse the area with warm water and dry it thoroughly with a soft cloth.
