How to Remove Roofing Tar from Metal
Roofing tar can be stubborn to remove from metal surfaces, but with the following steps and tools, you can effectively clean and restore your metal to its original condition:
1. Gather Your Materials
Before you begin, gather the necessary materials for the job:
- Protective Gear: Wear gloves, safety goggles, and old clothing to protect yourself from tar and cleaning agents.
- Cleaning Solvent: Choose a solvent suitable for removing tar from metal, such as mineral spirits, acetone, or a commercial tar remover.
- Scrapers: Use plastic or metal scrapers to gently lift and remove the tar without damaging the metal surface.
- Clean Cloths: Have clean, absorbent cloths or rags on hand to wipe away loosened tar and solvent.
- Brushes: Soft-bristled brushes or toothbrushes can help scrub away stubborn tar residues from crevices or textured surfaces.
2. Test in an Inconspicuous Area
Before applying the solvent or cleaner, test it in a small, inconspicuous area of the metal surface to ensure it doesn’t cause damage or discoloration.
3. Apply the Cleaning Solvent
Apply the chosen cleaning solvent directly to the tar-stained areas of the metal:
- Pour or Spray: Depending on the solvent type, pour it directly onto the tar or use a spray bottle to apply a generous amount.
- Soak and Soften: Allow the solvent to soak into the tar for several minutes to soften it and make it easier to remove.
4. Scrape Off the Roofing Tar
Once the tar has softened, use a scraper to gently lift and remove the tar from the metal surface:
- Angle the Scraper: Hold the scraper at a shallow angle to avoid gouging or scratching the metal.
- Work in Sections: Work in small sections, applying more solvent as needed, and continue scraping until the tar is completely removed.
5. Clean and Rinse
After scraping off the tar, clean the metal surface to remove any remaining residue and solvent:
- Use Clean Cloths: Wipe the surface with clean cloths or rags soaked in water to remove loosened tar and solvent residues.
- Rinse Thoroughly: Rinse the metal surface with clean water to wash away any remaining traces of tar and solvent.
6. Repeat if Necessary
For stubborn tar stains or residues, repeat the solvent application and scraping process until the metal surface is clean and free of tar.
7. Polish and Protect
Once the metal is clean and dry, consider polishing and protecting it to restore shine and prevent future tar adhesion:
- Metal Polish: Use a metal polish or wax to buff the surface and restore its luster.
- Protective Coating: Apply a protective coating or sealant designed for metal surfaces to guard against tar and other contaminants.
8. Dispose of Waste Properly
Dispose of used cloths, rags, and leftover solvent according to local regulations and environmental guidelines.
