Rust eraser
The presto rust eraser is excellent for removing rust from small rust spots.
Due to the fine fiberglass fibers (no wire) intact paint surfaces are not getting damaged - there are no scratches / abrasion marks. Because of the large effect of extremely hard fiberglass any rust is thoroughly removed.
Even for non-scratch solving oxidation on electrical contacts (eg electronic components, mobile phones, etc.). No short circuit risk, as metal-free.
