Yes, it is possible to remove rust from anything and keep it away in most cases. I will demonstrate on an old hammer today, but I have successfully removed it from quite a few other things in the past, like nuts and bolts, and garden tools etc.You need just one magic ingredient; white vinegar for this purpose. You can use apple cider or any other fancy vinegar too, but white vinegar is the cheapest and rust does not mind it. Immerse the rusted object fully in vinegar. On large objects, which are hard to immerse, you can cover the rusted area with a paper towel or even some rag soaked in vinegar. In nutshell rust should be in constant contact with vinegar.Leave it covered in vinegar overnight, or for a few hours. you will see the rust separating from the object. See small particles at the base of the bowl.
Scrub the loosened up rust with some hard bristle brush. I have a denture cleaning brush from a Dollar store for such jobs, but any other brush would do. I have even used a shower loofah for this purpose too in the past.
All the rust removed.
Give it a good bath to clear away any remaining rust particles.
All clean. But the rust has a tendency to return. Best way to keep it away is to give the newly de-rusted object a protective coat.
I usually wax my tools after removing the rust with the paste was shown in the picture below. If there is a chance that your object might come in contact with the food, then don’t use this wax. I would recommend some butcher block refinishing wax or any food safe wax.
Apply wax as per the instructions on the package.
That’s it. My hammer is good as new with more years added to its life.
One last shot of before and after.I would like to know if you have used any other method to remove the rust.
