What Can Remove Paint From Metal Surfaces?

Fortunately, metal is porous, which means it is not that difficult to remove unwanted spray paint. The challenge you will face is trying to remove it without damaging the surface underneath the paint.

There are a variety of ways you can remove spray paint from metal surfaces that you can choose from. Let’s take a closer look:

Chemical Removers

Various types of chemicals can be used to remove spray paint from metal surfaces. Here are the most common chemical paint removers used:

  • Paint stripperor liquid paint remover

    Liquid paint remover is ideal for small items like brass knobs or metal hardware. You would soak the items in the liquid paint remover then use a stiff bristle brush to scrub off the loosened paint. Make sure todispose of paint thinner properlyafter using.

  • Spray-on paint removers

    This type of chemical comes in an easy-to-use spray bottle. It is ideal for spraying on surfaces that can't be soaked, such as rounded surfaces on bikes and patio furniture. You can find it at automotive stores.

  • Brush-on gel remover

    If you have thick paint on a metal surface, you would want to use the gel-type paint remover. This is because the gel doesn’t evaporate the way liquid remover does. So,you can leave it on longer.

  • Carnauba wax

    Carnaubawax is ideal for the metal on vehicles. It comes in aerosol or liquid and is specifically designed to dissolve acrylic spray paint on vehicles without damaging the coat underneath it.

Blasting

There are two ways of blasting spray paint off of metal surfaces. Blasting uses a blasting rig to remove spray paint from large projects such as construction or farm equipment. You can either use sandblasting or soda blasting. Let's take a look at the differences:

  • Sandblasting

    Sandblasting uses sand particles to scrape the surfaces by blasting them with small particles propelled at high pressure.

  • Dustless sandblasting

    This process uses sand just like sandblasting; however, you also add water and typically a rust inhibitor with it to minimize the dust.

  • Soda blasting

    Soda blasting uses sodium bicarbonate, also known as baking soda, to blast the spray paint particles away.
