Stainless steel screws are used frequently in daily life, but they are prone to rust after a long time. If it is rusted, how to loosen the stainless steel screws. Use the following aspects to solve:
Method one: knock
Severely rusted screws should not be hardened with a wrench to prevent them from slipping and cornering, twisting the screws or screwing the wrench. At this point, you can tap the handle of the wrench with a hammer, and the rusted screws will often loosen to unscrew.
Method two: drop
If the screw is not severely rusted, you can try to drip first. If you can't open it, you can drop a little oil or vegetable oil along the gap between the screw and the nut. With wire cutters and wrenches, you can easily unscrew it. (The oil does not work for rusted screws and will affect disassembly)
Method three: burn
