There are various methods to eliminate paint from aluminum siding without causing too much trouble. You can use things like Goof Off, vinegar, or baking soda, paint stripper. Another option is to use something called methyl ethyl ketone to get rid of oil-based paint on your aluminum siding.

Method 1: Using Goo Gone to Remove Paint from Aluminum:

Prepare Materials:

Gather the necessary materials, including Goo Gone, paper towels, and water. Ensure you have a sufficient supply of paper towels for the job.

Apply Goo Gone:

Dampen a section of the paper towel with Goo Gone. Carefully apply the Goo Gone to the painted area on the aluminum surface.

Allow Penetration:

Allow the Goo Gone to rest on the paint for a brief period, enabling it to seep in and soften the paint.

Blotting Technique:

Use the paper towel to blot the paint gently. This helps to lift and absorb the softened paint. Repeat this process for several seconds, applying gentle pressure.

Scraping Process:

For more stubborn paint spots, use a paint stick to scrape off the softened paint. Be cautious not to damage the aluminum surface during this step.

Continue Until Removal:

Repeat the application of Goo Gone, blotting, and scraping until all the paint has been successfully removed from the aluminum. Be patient and persistent in areas where the paint adheres more stubbornly.

Clean Residue:

Dampen a fresh section of a paper towel with water and wipe down the aluminum surface to remove any remaining Goo Gone residue.

Inspect the aluminum surface to ensure all traces of paint have been effectively removed. If needed, repeat the process in specific spots until the surface is clean.

Use coarse sandpaper or abrasive pads to manually sand away the paint. Initiate the process with a coarser grit and progressively transition to finer grits for a smoother finish. This method may necessitate additional effort and time.

A wire brush proves effective in eliminating paint, particularly when it’s not excessively thick. Utilize a wire brush to scrub the painted surface until the paint is completely removed.
