Aluminum trim can be found on both the interior and exterior of many homes. This element can be used on window trim and gutter trim, and was commonly used in the construction of older homes. From time to time, you may wish to paint the aluminum to spruce up the home or paint the trim a new color to match the home's decor.
Scrub the aluminum with soapy water by combining 1 gallon of warm water and 1/4 cup of dish soap in a bucket.

Make sure the paint is safe for aluminum surfaces. Dip a paintbrush into the paint, and brush the paint onto the aluminum using long, even strokes.
