First, remove coarse dirt with a soft cloth or brush. Then use a wire brush to scrub the rust from the tool. Next, switch to a piece of sandpaper or steel wool and continue to scrub the rust from the tool. Start with the most rusted areas first. Afterwards, it is possible to prevent rust from forming again by treating your tools with tool oil, wax, camellia oil or special anti-rust pastes. Regularly lubricate machine parts and refill hydraulic oil.
