Light rust can build up on metal surfaces that are exposed to water, such as grills, fire pits and patio furniture. You can remove this rust using a rotary tool fitted with a brush or abrasive wheel and restore the metal to its original condition. It is important to remove rust as soon as possible. If left, the rust will eventually weaken the metal and require that it be replaced. You can prevent rust from occurring by keeping your metals coated with a rust protector such as paint.
Place the rotary tool on a work surface. Insert the carbon steel brush into the rotary tool chuck. Tighten the chuck with the chuck key.
Turn the rotary tool on and run it at high speed for approximately one minute to allow any loose or stray brush wires to come off from the wheel.
Lower the speed to medium-high and allow the brush to contact the rusted metal surface. Move the brush back and forth allowing it to contact the surface without applying a lot of pressure. Keep the motion of the tool steady as you gradually remove the rust.
Turn the rotary tool off. Remove the steel brush and insert an aluminum oxide abrasive wheel into the rotary tool to remove deeper areas of rust. Turn the tool on and apply light pressure to the rusted surface as you move the wheel back and forth over the rust in an even motion. Continue in this manner until all of the rust has been removed.
Tips & Warnings
- Coat the metal with a rust preventative such as metal rust protecting paint.
- Wear eye and ear protection when operating a rotary tool.
