Rust on the screw will seriously affect the normal use of the jack, so what better method do we have for rust removal? Now, Guanghang offers you two suggestions.

First: We can invade oil on the screw thread, which is a classic "oil rust removal" method. The use of diesel, gasoline, kerosene can play a role. If the rust is not very severe, you can drop a few drops of oil on the gap of the thread, and then slowly try to turn the screw when the oil invades the inside of the thread. If the screw is seriously rusted, it is necessary to slightly tighten the screw, and then repeat the screw with appropriate oil dripping. Do not act too quickly.

Second: We can adopt weak acid rust removal method. If there is no professional rust removal solution, we can also use our vinegar. It is the same as the cola and oxalic acid we usually drink. It can also remove rust. Use the same way as oil. A few drops of vinegar or oxalic acid can also decompose the iron oxide at the rusty position of the thread end. This method is only applicable to screws with slight corrosion. If the corrosion is serious, this method may not be effective.
