DIY projects can quickly come to a halt if you encounter an old bolt that's so rusty you're having a hard time using your screwdriver or spanner to remove it. When faced with heavy rust, it’s challenging to determine which tools you’ll need for the job. Fortunately, there's no need to abandon your project if you have a can of Coca-cola to hand. This soda acts as a loosening agent.
You can soak a rusted bolt in Coke or use a scrubbing sponge doused with Coca-cola. Either way, the acid in the drink should cut through the rust and help you undo the bolt.
