Acetone can be used to clean fiberglass surfaces effectively. Here are the steps to clean fiberglass with acetone:

1. Wear protective gloves and work in a well-ventilated area.

2. Start by removing any loose dirt or debris from the fiberglass surface.

3. Moisten a clean cloth or sponge with acetone.

4. Gently scrub the fiberglass surface with the acetone-soaked cloth or sponge, applying light pressure.

5. Continue scrubbing until the surface is clean, paying extra attention to any stubborn stains or grime.

6. Rinse the fiberglass surface thoroughly with water to remove any residue.

7. Dry the surface completely with a clean towel or allow it to air dry.

Remember to test a small, inconspicuous area first to ensure that the acetone does not damage or discolor the fiberglass.

It not only cleans dirt and grime off fiberglass surfaces, but also gets rid of stubborn stains like rust and pen marks.
