What cleaning tool can be used with an air or electric drill to remove old gasket material?

An abrasive pad is designed specifically for use with power tools like air or electric drills and is effective in removing stubborn materials such as old gasket residue. These pads are composed of materials that can effectively scuff or grind away the old gasket material without damaging the underlying surfaces. This makes them particularly useful in automotive applications where a clean, flat surface is necessary to ensure a proper seal for new gaskets. Their compatibility with drills allows for efficient removal, saving both time and effort compared to manual methods.

The other tools mentioned do not serve the same purpose effectively. A ball peen hammer is primarily used for shaping metal and may damage components if applied to gasket material. A scratch awl is more suited for marking or starting holes rather than for removing material. A pry bar is intended for leveraging or prying apart components, which would not be adequate for the delicate task of cleaning surfaces to prepare for new gaskets. Therefore, the abrasive pad is the optimal choice for the task specified.
