The easiest way to clean Bondo is to mix equal parts of paint stripper and water. Soak a rag in the solution and scrub the Bondo off the surface. If there are large areas of dried Bondo, you may need to apply more than one coat of paint stripper to get it completely cleaned.

Once the Bondo is removed, use a steel wool pad to polish the surface. Finally, dry the surface with a clean rag.

If the Bondo is stubbornly stuck on, you can try using lemon juice or vinegar on a cloth. Wet the cloth, place it over the Bondo, and rub it until it starts coming off.

Different Types of Bondo

There are many different types of Bondo, so it’s important to know the difference before you start cleaning it. The most common type is wood filler, which is used to fill cracks and holes in wood. It’s a very thick paste that needs to be sanded smooth before it can be painted.

Bondo also comes in other forms, like Plaster of Paris, a flexible putty used for sculpting and modeling. It needs to be cleaned just like Bondo, but it must also be dried completely before painting.
