Many engineering tools accumulate rusts in the long run that may lead to unwanted events such as broken bolts. This is the most common issue if they were not used for a long time. The same issue goes with other tools such as snips and screws. Today, many processes are being introduced in order to make a DIY (do-it-yourself) rust removal. Let me guide you with the simplest process.
Chemically-Based with Manual Rust Removal
Many people would tell you that anyone can easily remove rust from any tools with the use of vinegar, especially, an apple cider vinegar solution. Accordingly, soaking the rusted tools under the apple cider solution overnight in addition to a mild manual brushing can get the job done. In the video below, the shear bolts were tested for rust removal with the use of the regular white vinegar we can easily find in our household.

Basically, leaving these tools soaked under the vinegar will not do the trick easily. This is why it is extremely important to add the manual rust removal method which is to scrub the rust with the use of a metal brush. This will help you remove the rust in about an hour with remarkable results. With the combination of these simple methods, you do not need to spend more for a replacement because these steps can be done as easy as one-two-and-three.
