Have you tried your best to open rusty bolts and screws, but failed every time? Do not worry. This is a very common story and almost everyone has been through such a situation at some point in their lives.
In particular, these bolts and screws will soon rust if exposed to moisture for a long time. And once it’s rusted, it’s often very difficult, if not impossible, to unscrew. For example, screws and bolts in car parts, boats or lawn mowers are almost always exposed to moisture and therefore often rust. And the biggest problem is that it’s difficult to avoid moisture. The problem gets worse when the Cleaner Laser gets into the threads or when rust eats away at the screw’s metal head, making it difficult to grip with a screwdriver.
Sometimes you can just throw away rusty screws and grime, but most of the time your local hardware store won’t be able to replace many of them, so you’ll have to restore the old ones. In these situations, it is important to be able to properly clean screws and bolts so that they can be reused after cleaning.
People make various attempts in similar situations to remove rust and open screws and other metal bodies. Some of them are effective and some have no proven track record. Here are some common methods people use to effectively remove rust.
The most common solution is to use penetrating oil purchased from a local hardware store. What you need to do in this situation is to put a few drops of penetrating oil on the screw, let it sit for a while and then use a screwdriver to open it. You may have to use a narrow chisel and hammer to move the rusty screws in if needed. You may need to leave the screw in penetrating oil overnight if the condition is too poor. Loosen up by morning. This is a much used process for removing rust, but it is not very effective.
Some people prefer to use hydrogen peroxide on rusty screws and bolts. They pour some hydrogen peroxide on the screws and bolts and leave it there. After a while you should use a hard brush to remove the rust from the screws. You may need to use a little oil after cleaning the rust to make the screw come out easier. Hydrogen peroxide is always best avoided as it often leaves some residual elements in its place.
Another common and effective solution is to use a Laser Metal Cleaner. You can easily find good quality rust remover at some local stores, or you can order it online. A good quality rust remover does not require scrubbing and brushing. All you need to do is dip the rusted metal into the cleaning solution. However, it is always a good idea to buy an organic rust remover for other uses as well.
If you want to do it the harder way, use fine sandpaper to sand off all the rust on the screws and bolts. But don’t forget to apply some lube before reuse.
