When removing spray paint from a surface without damaging the underlying paint, it's important to use gentle methods and test them in inconspicuous areas first. Here are some techniques you can try:
Soap and Water: Start by using a mild soap and warm water solution. Gently scrub the painted surface with a soft cloth or sponge. This method works best for fresh spray paint and can help remove it before it fully dries.
Rubbing Alcohol: Apply a small amount of rubbing alcohol to a clean cloth and gently rub the affected area. Test it first in an inconspicuous spot to ensure it doesn't damage the paint. Alcohol can dissolve some types of spray paint, but avoid using excessive force to prevent damage.
Acetone or Nail Polish Remover: Acetone can be effective in removing spray paint, but it's stronger and more likely to damage the underlying paint. Test it in an inconspicuous area first and apply it sparingly using a cotton ball or cloth. Rinse the area with water afterward.
Paint Thinner: Paint thinner, such as mineral spirits or turpentine, can also be used cautiously. Apply a small amount to a cloth and gently rub the affected area. Like acetone, it has the potential to damage the underlying paint, so test it first and use it sparingly.
Commercial Graffiti Removers: There are specialized graffiti removers available in the market that are formulated to remove spray paint without damaging the underlying paint. Follow the instructions provided by the manufacturer and test them in an inconspicuous area first.
Remember to wear gloves and work in a well-ventilated area when using solvents. Always follow the manufacturer's instructions and exercise caution to prevent any unintended damage to the painted surface. If you're unsure or dealing with a delicate surface, it's advisable to seek professional advice or consult a painter.
