Q: How can I clean the rust from screw heads and other uneven surfaces?
A: Grab a tooth brush with medium stiff bristles and some cleaner wax. Pour a very small amount of cleaner wax over the screw and use the toothbrush to work it in. Let it dry to a haze (this is why you only use a small amount) and then take a different toothbrush with softer bristles and use it to clean out the wax from the screw head. Then wipe away completely with a microfiber rag. Not only will this remove light to medium rust stains, but it will also protect the metal and prevent them from coming back over time. To further protect the screw heads once you’ve removed the rust, simply apply spray wax to them and wipe off.
